The Lewis definitions include all Brønsted-Lowry acids and bases. According to Lewis, an acid accepts an electron pair during a reaction and a base donates an electron pair.
Strong/Weak_Acid/Base
This document discusses acids and bases, distinguishing between strong and weak acids/bases as well as concentrated and dilute solutions. Strong acids and bases fully dissociate in water, while weak ones only partially dissociate. Concentrated solutions have high amounts of solute per liter, while dilute solutions have low amounts. Common strong acids and bases are listed. Strong acids/bases have more extreme pH values and higher conductivity than weak ones when at the same molarity. Acidic and basic salts can form depending on if the salt is made from a strong acid/weak base or strong base/weak acid. Neutral salts form from strong acids and bases.
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.

Acid bases and salts.part 2
This document provides an overview of acids and bases according to the Arrhenius and Brønsted-Lowry theories. It discusses how acids and bases were originally categorized based on their physical properties. The Arrhenius theory defined acids as substances that produce H+ ions in water and bases as substances that produce OH- ions. It also explains that H+ ions actually exist as hydronium ions (H3O+) in water. The Brønsted-Lowry theory expanded this to define acids as proton donors and bases as proton acceptors. Other topics covered include strong vs. weak acids/bases, the autoionization of water, and the pH scale.
6.1 Role of water in showing acidic and alkaline properties (PPT)
This chapter discusses acids, bases, and salts. It defines acids as substances that produce hydrogen ions (H+) in water, and bases as substances that react with acids to produce salts and water. Alkalis are soluble bases that produce hydroxide ions (OH-) in water. The chapter covers acid-base theories, pH, strength of acids/bases, concentration of solutions, neutralization reactions, and preparation and properties of salts. Examples of uses of acids and bases in daily life are discussed, such as sulfuric acid in car batteries and sodium hydroxide in soaps.
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.

Redox Reaction
Redox reactions involve the transfer of electrons between substances, causing some substances to be oxidized (lose electrons) and others to be reduced (gain electrons). In the examples given, sodium metal is oxidized when it reacts with bromine gas, losing electrons to become sodium ions. Bromine gas is reduced, gaining electrons to become bromide ions. Zinc metal also undergoes oxidation when reacting with hydrochloric acid, losing electrons to form zinc ions, while hydrogen ions are reduced, gaining electrons to form hydrogen gas. Oxidation numbers are used to indicate the charge of atoms in their elemental or ionic states and can help identify whether a substance is being oxidized or reduced in a redox reaction.
Acids Bases and Salts
Acids release H+ ions in water and have sour tastes, while bases release OH- ions in water and feel slippery. Strong acids and bases completely ionize in water, while weak acids and bases only partially ionize. Common strong acids include sulfuric acid and hydrochloric acid, while strong bases include lithium hydroxide and sodium hydroxide. When acids and bases are mixed, they neutralize each other through a reaction that produces water and a salt. Indicators change color depending on whether the solution is acidic or basic, and can be used to measure the pH of a solution.
Arrhenius
The document discusses Arrhenius's theory of acids and bases. It defines acids as hydrogen-containing compounds that yield hydrogen ions (H+) in solution, and bases as compounds that yield hydroxide ions (OH-) in solution. It provides examples of common acids like hydrochloric acid and sulfuric acid, as well as bases like sodium hydroxide. It classifies acids based on the number of ionizable hydrogens they contain as mono-, di-, or triprotic. The document also discusses the properties of acids and bases and their reactions in aqueous solutions.
Acid and base theories
This document discusses acids and bases. It begins by defining the objectives of understanding acid and base definitions and theories. It then provides examples of common household and laboratory acids and bases. Next, it explains the Arrhenius theory that acids dissociate in water to form H+ ions and bases dissociate to form OH- ions. It also discusses the Brønsted-Lowry theory that acids donate protons and bases accept protons. Neutralization reactions between acids and bases to form salts and water are then explained. The document concludes by discussing acid-base conjugate pairs and examples.

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.
Antacids
The document summarizes antacids, which are bases that neutralize excess stomach acid. It discusses how the body regulates pH and the issues caused by too much acid, such as indigestion and ulcers. Common antacids contain metal hydroxides or carbonates that react with hydrochloric acid in the stomach. While antacids temporarily relieve symptoms, they should only be taken short-term without medical advice due to potential side effects and drug interactions.
Chapter 15.1 : Properties of Acids and Bases

Acidic oxides dissolve in water to form acids, basic oxides are insoluble in water and react with acids to form salts, amphoteric oxides react with both acids and bases, and neutral oxides do not react with acids or bases. Common examples of each type and their reactions are provided.
