An acid is a chemical substance that produces hydrogen ions (H+) in water, while a base reacts with an acid to produce salt and water. Strong acids fully ionize in water to produce a high concentration of H+ ions, while weak acids only partially ionize, producing a low H+ concentration. Strong bases fully ionize to produce a high concentration of hydroxide (OH-) ions, unlike weak bases. Acids have sour tastes, turn litmus paper red, and are electrolytes in water. They react with metals, bases, carbonates, and alkalis to produce salts, hydrogen gas, water, and carbon dioxide. Bases have bitter tastes, turn litmus paper blue, and are electrolytes

Acids And Bases
This document provides information about acids and bases, including their properties and reactions. It defines acids as substances that produce hydrogen ions in aqueous solution, and bases as metal oxides or hydroxides. Strong acids are fully ionized in water, while weak acids are only partially ionized. The strength of an acid does not relate to its concentration. Common uses of acids include battery electrolytes, rust removal, and food preservation.
Buffers
Buffers resist changes in pH upon the addition of small amounts of acid or base. They work by neutralizing added acid or base through chemical reactions. There are two main types of buffers - acidic buffers which use a weak acid and its salt, and basic buffers which use a weak base and its salt. The pH of buffer solutions can be calculated using the Henderson-Hasselbalch equation. Buffer capacity is a measure of a buffer's ability to resist pH changes and depends on the buffer components and their concentrations. Buffers have many important applications, including maintaining the pH of blood and pharmaceutical products.
Acids, bases and salt
This document defines acids, bases, and salts according to three theories:
1) Arrhenius defines acids as substances that yield hydrogen ions in water and bases as substances that yield hydroxide ions in water. Neutralization produces salt and water.
2) Bronsted-Lowry defines acids as proton donors and bases as proton acceptors. Neutralization involves the transfer of a proton from an acid to a base.
3) Lewis defines acids as electron pair acceptors and bases as electron pair donors. Neutralization involves the sharing of an electron pair between an acid and base.
Hardness of water
This document discusses hardness of water. It defines hardness as being caused by calcium and magnesium ions which can be temporary (removed by boiling) or permanent. It describes common methods to determine water hardness, including soap titration and EDTA methods. Hardness is expressed in units of calcium carbonate equivalent by multiplying the weight of ions by their molecular weights.

Primary and secondary standard
The document discusses primary and secondary standards. A primary standard is a compound that is sufficiently pure such that a standard solution can be directly prepared by weighing and diluting the compound. It must be easy to obtain, purify, dry, store, and test for impurities. Sodium carbonate, sodium tetraborate, and benzoic acid are provided as examples of primary standards for acid-base, complex formation, and oxidation-reduction reactions respectively. A secondary standard is a substance whose concentration has been determined by comparison to a primary standard solution, rather than direct weighing. Hydrated salts generally do not make good standards due to drying difficulties, but some like sodium tetraborate do not effloresce and can
bronsted-lowry concept of acids and bases
Bronsted and Lowry introduced the concept of acids and bases in 1923. According to Bronsted-Lowry theory, an acid is a proton donor and can donate a hydrogen ion to another molecule, while a base is a proton acceptor and can accept a hydrogen ion from another molecule. The conjugate acid of a base is the molecule formed when the base accepts a proton, while the conjugate base of an acid is the molecule formed when the acid donates a proton. Water is provided as an example of an amphoteric substance that can act as both an acid and a base by donating or accepting protons.

Common acids and bases are used in products like cleaners, soaps, batteries, and more.
harness of water ppt
Alkalinity in water is measured by titrating a water sample with sulfuric acid and monitoring the pH. Alkalinity is caused by hydroxides, carbonates, and bicarbonates and is expressed in units of mg/L of calcium carbonate. The amount of acid needed to reduce the pH to 8.3 measures phenolphthalein alkalinity, while the amount to reduce to 4.5 measures total alkalinity. Different combinations of hydroxides, carbonates, and bicarbonates can be present depending on the initial pH. Alkalinity data provides information useful for water treatment processes like coagulation, softening, and corrosion control.

Acid base notes
This document discusses acids and bases. It defines acids as substances that produce hydrogen ions in water, and bases as substances that produce hydroxide ions in water. Strong acids and bases completely ionize, while weak ones only partially ionize. Neutral substances have equal concentrations of hydrogen and hydroxide ions. When acids and bases are mixed, they neutralize to form salts and water through balanced chemical reactions. pH indicators can be used to determine if a solution is acidic, basic, or neutral.
Importance of chemistry in daily life
Chemistry plays an essential role in life on Earth. Organisms use chemicals to survive in extreme climates through enzymes that protect membranes. The human body also relies on chemistry, using chemicals to break down food and produce mucus layers that protect organs. While chemicals are necessary for life, they can also pose harm, like stomach acids. Synthetic materials created through chemistry have benefits over natural materials by combining desirable properties without negatives. However, chemical reactions used to make synthetics can also be dangerous, so safety precautions must be followed.
Acids and Bases
Acids are substances that donate protons (H+) in aqueous solutions, increasing the concentration of H+ ions. Common acids include HCl, HNO3, and HC2H3O2. Bases are substances that accept H+ ions, producing hydroxide (OH-) ions when dissolved in water. Common bases include NaOH, KOH, and Ca(OH)2. Strong acids and bases are completely ionized in solution, while weak acids and bases are only partially ionized. The strength of an acid or base determines how reactive it is.
11 Buffers
The document discusses buffers and how they maintain pH levels in the blood. It specifically focuses on the carbonic acid-bicarbonate buffer system, which is the most important buffer. This buffer system involves the equilibrium between carbonic acid, which donates hydrogen ions, and bicarbonate ions, which accept hydrogen ions. This helps regulate pH levels and protects against changes that could be harmful or fatal.
Chemical composition of water by Group 2
Water is the most abundant compound on Earth, covering 70% of the planet's surface. It exists naturally as a liquid, solid (ice), and gas (water vapor) and is essential for life. Water has unique physical properties including being transparent, colorless, virtually odorless and tasteless as a liquid. It has a high heat capacity and heat of vaporization due to extensive hydrogen bonding between molecules. These properties allow water to moderate the Earth's climate. Water plays a vital role in all living organisms, making up 55-78% of the human body.
arrhenius concept of acids and bases
According to Arrhenius' concept of acids and bases presented in 1887, acids are substances that dissociate in water to produce hydrogen ions, while bases are substances that dissociate in water to produce hydroxide ions. Examples given are that HCl produces H+ ions in water to act as an acid and KOH produces OH- ions to act as a base. However, this concept has limitations in that it only applies to substances in water and cannot explain the behavior of acids and bases in non-aqueous solutions or compounds without H+ or OH- ions like CO2 and NH3.
chemical Indicators
Indicators are chemical substances that change color based on whether a solution is acidic or basic. Common acid-base indicators include litmus, methyl orange, and phenolphthalein. They change color at specific pH levels, allowing for the determination of a solution's acidity or basicity. Other types of indicators include universal indicators, which change color gradually over a wide pH range, olfactory indicators detected by smell, and redox indicators sensitive to oxidation-reduction reactions. Indicators find uses in titrations, testing soils and swimming pools, and monitoring wastes.
pH indicator
The document defines pH as the negative logarithm of the hydrogen ion (H+) activity in a solution, with the pH scale ranging from 0 to 14. The hydrogen ions determine if a solution is acidic, alkaline, or neutral - if the hydrogen ion content is measured, the acidity or alkalinity can be determined. Water molecules dissociate into hydrogen and hydroxide ions through autoionization, affecting pH. pH indicators change color depending on the pH of a solution, allowing determination of acidity or alkalinity.

Theory of Acid-base Indicators and Acid-base Titration Curves
1) Acid-base indicators change color at a specific pH range near the equivalence point of an acid-base titration. This allows the endpoint to be visually identified.
2) The pH curve for a strong acid-strong base titration shows a sharp change in pH at the equivalence point of 7. A weak acid-strong base titration has a more gradual pH change before and after the equivalence point, which is above 7 due to salt hydrolysis.
3) The suitable indicator depends on the pH changes around the endpoint. It must change color in the steep "vertical" portion of the curve to accurately identify the endpoint.
Dissolved Oxygen Demand (DO) AND Chemical Oxygen Demand (COD) PDF
Dissolved oxygen (DO) refers to the level of oxygen present in water or other liquids. It is important for assessing water quality and supporting aquatic life. Chemical oxygen demand (COD) measures the amount of oxygen required to chemically break down pollutants in water. DO enters water through diffusion from air and as a byproduct of photosynthesis. It can be measured using electrochemical, optical, or colorimetric methods. COD is determined by using potassium dichromate as an oxidizing agent under acidic conditions, then measuring the amount of chromium formed.
Indicators
This document discusses pH and indicators. It explains that pH is a measure of acidity or alkalinity on a scale from 0 to 14, with acids below 7 and alkalis above. It describes common tools to measure pH like pH papers, meters, and dataloggers. It also defines indicators as substances that change color based on pH and lists common natural and synthetic indicators like litmus, universal indicator, methyl orange, and phenolphthalein.
Role of chemistry in every day life
This document discusses the role of chemistry in everyday life. It notes that chemistry is important in areas like food, medicine, diseases, and daily activities. The human body itself is largely composed of chemical compounds - roughly 96% of the human body's mass is made up of just four elements: oxygen, carbon, hydrogen and nitrogen. Chemistry helps in understanding vitamins, supplements, and how drugs can help or harm the body. It also plays a role in medical research to understand diseases on a molecular level.
Acids and Bases
This document discusses the chemistry of acids and bases. It outlines three definitions of acids and bases: Arrhenius, Brønsted-Lowry, and Lewis. The Arrhenius definition states that acids produce hydrogen ions in water and bases produce hydroxide ions. The Brønsted-Lowry definition broadened this to include acids as hydrogen ion donors and bases as acceptors. The Lewis definition focuses on electron pair donation and acceptance. Acids react with bases to form salts and water in a neutralization reaction. Common acids include sulfuric acid, nitric acid, hydrochloric acid, and acetic acid.
Ph scale
Water undergoes self-ionization in which a small percentage of water molecules dissociate into hydronium (H3O+) and hydroxide (OH-) ions. The concentration of these ions is extremely small and the equilibrium lies very much in the forward direction. The self-ionization of water can be represented by the equilibrium constant Kw, which is equal to the product of the hydronium and hydroxide ion concentrations. Kw is temperature dependent and decreases with increasing temperature. The pH scale was developed to quantify the concentration of hydronium ions in solution and thus indicate whether a solution is acidic, basic, or neutral. pH is defined as the negative logarithm of the hydronium ion concentration
Type of electrodes
This document describes the electrolysis of a copper(II) sulfate solution using copper electrodes. During electrolysis, copper ions and hydrogen ions move to the cathode where copper ions are discharged to form a brown copper deposit, while hydroxide and sulfate ions move to the anode where the copper electrode dissolves to release copper ions and electrons. The process results in the cathode gaining mass and thickness while the anode loses mass and becomes thinner, but the concentration and blue color of the copper ions in the solution remains unchanged.
Concentration of ions in the solution
The document describes the electrolysis of a 1.0 mol/dm3 sodium chloride solution using carbon electrodes. During electrolysis, sodium and chloride ions move to the cathode and anode respectively. At the cathode, hydrogen ions are discharged to produce hydrogen gas while at the anode, chloride ions are discharged to produce chlorine gas. The solution becomes alkaline after electrolysis due to the presence of sodium hydroxide.

Round robin english
This document contains information about chemistry concepts taught using the "Round Robin" method. It includes 8 sections called PINTAR that cover topics like solubility rules for salts, reactions to form salts, tests to identify cations, and the behavior of salts when heated. The purpose is for students to memorize the content through repeated oral recitation of the sections in a round-robin style until all students have memorized the full content.
Electrolyte
Electrolytes are substances that can conduct electricity when molten or dissolved in water, as they dissociate into ions that are free to move. Non-electrolytes do not contain ions and cannot conduct electricity either when molten or dissolved. While solid ionic compounds cannot conduct due to their tightly bound ions, they can conduct in molten or aqueous states as their ions gain freedom of movement.
Electrolysis molten sodium chloride
The document summarizes the process of electrolysis for two types of electrolytes: molten sodium chloride and aqueous electrolytes. For molten sodium chloride, sodium and chloride ions move to the cathode and anode, respectively, where they are discharged. Sodium forms at the cathode while chlorine gas forms at the anode. For aqueous electrolytes like dilute sulfuric acid, hydrogen, sulfate, and hydroxide ions are present and migrate to the electrodes where hydrogen gas forms at the cathode and oxygen gas forms at the anode.
Electrolysis of molten compounds
Electrolysis is a process where an electrolyte is broken down into its constituent elements when electricity passes through. An electrolytic cell converts electrical energy to chemical energy using a battery, electrolyte, and two electrodes. During electrolysis, anions move toward the anode and cations move toward the cathode, where they are discharged by gaining or losing electrons.

Buffer Systems and Titration
Mathematical background of buffer systems and alkalimetric titration (with examples for the carbonate system).
Composite Carbonic Acid and Carbonate Kinetics
There are two types of carbonic acid: true carbonic acid (H2CO3) and composite carbonic acid (H2CO3*). True carbonic acid involves the direct reaction of CO2 and H2O, while composite carbonic acid treats CO2(aq) and H2CO3 as a single entity. Each acid has its own equilibrium constant (Ktrue and K1). K1 is around 500 times smaller than Ktrue due to the inclusion of dissolved CO2 in the composite definition.
