Magnesium reacts with hot water but not cold water. Less reactive metals like aluminum, iron and zinc only react with steam, producing metal oxides and hydrogen gas. Some metals like lead, copper, silver and gold do not react at all with water, steam or heat.
8.3 reactions in aqueous solutions
This document discusses reactions in aqueous solutions. It defines key terms including electrolytes, nonelectrolytes, dissociation, and ionization.

Reactions in aqueous solutions can form precipitates when mixing two solutions yields an insoluble product. Molecular and ionic equations are used to represent chemical reactions, and net ionic equations show only the spectator ions.
Redox reactions at electrodes
During electrolysis, redox reactions occur where ions are reduced or oxidized at the electrodes. At the cathode, ions gain electrons through reduction reactions and at the anode, ions lose electrons through oxidation reactions. The overall reactions in electrolysis depend on the electrolyte, with common products including hydrogen, oxygen, chlorine and metals.

Acids and bases can be classified based on their strength. Strong acids and bases fully dissociate in solution, while weak acids and bases only partially dissociate. The strength of an acid or base depends on factors like the polarity and stability of the conjugate ions. Acid-base reactions involve the transfer of protons between substances. The pH scale quantifies the concentration of hydrogen ions in a solution, relating acidity to the logarithm of the hydrogen ion concentration. Salts are formed by the neutralization of acids and bases.

Metallurgy
Metallurgy involves extracting metals from their ores in their pure state. Most reactive metals are found combined as sulfates, carbonates, or oxides, while less reactive metals occur naturally in their free metallic state. The process of metallurgy includes mining ores, concentrating the ores to remove impurities, oxidizing and reducing the ores, and refining the reduced metals. Electrolytic refining is used to remove soluble and insoluble impurities from reduced metals to produce pure metals.

The reaction is balanced by accounting for the moles of each element based on their subscripts.
Redox reactions
Oxidation involves the loss of electrons or gain of oxygen by an atom or molecule, while reduction is the gain of electrons or loss of oxygen. Redox reactions involve the transfer of electrons between oxidizing agents that gain electrons and reducing agents that lose electrons, with oxidation occurring at one molecule and reduction at the other. Redox reactions are chemical reactions where oxidation and reduction processes simultaneously occur through electron transfer between two reacting species.

The type of electrode and competing ions determine which ions are discharged or undergo other chemical changes at each electrode along with the products observed.
uses of salts
Salt has many industrial uses beyond just food seasoning. Only 6% of manufactured salt is used for food, while the rest is used to make products like plastic, paper, glass, rubber, fertilizers, bleach, soaps, and dyes. Salt is crucial for many industries, as over 50% of chemical products depend on salt at some stage of production. It is also used in manufacturing glass, paper, rubber, textiles, and for water softening. Salt has been extracted and traded for thousands of years and was important culturally and economically for many ancient societies.
Introduction to ElectroChemistry
Electrolytes are substances that can conduct electricity when in a molten or aqueous solution state because they dissociate into ions. Examples include NaCl. Non-electrolytes cannot conduct electricity in any state and remain as covalent compounds, such as CCl4. When electricity flows through an electrolyte, the ions are attracted to the electrodes, allowing the flow of electrical charge and completing the circuit. This occurs because electrolytes contain freely moving ions, unlike non-electrolytes.

Electrolysis is the process of using a direct electric current to drive nonspontaneous chemical reactions. It involves the decomposition of an electrolyte into its constituent ions by the removal or addition of electrons to the ions. During electrolysis, ions migrate to the electrodes where they undergo oxidation or reduction reactions. In the electrolysis of molten lead bromide, lead ions are reduced to metallic lead at the cathode, while bromide ions are oxidized to bromine gas at the anode. When an aqueous solution of copper sulfate is electrolyzed using copper electrodes, copper ions are reduced at the cathode to form metallic copper while oxygen gas forms at the anode.

ELECTRO CHEMISTRY (1).pptx
Electrochemistry is the study of chemical reactions caused by electricity or that produce electricity. An electrochemical cell converts chemical energy into electrical energy and vice versa. There are two main types of electrochemical cells: (1) Galvanic/voltaic cells where a spontaneous redox reaction produces electricity, and (2) electrolytic cells where electricity drives a non-spontaneous reaction. Conductometric titration measures the change in conductivity during a titration reaction and can be used to determine the endpoint. The conductivity changes differently based on whether the acid and base are strong or weak.

Ions in solution
some basics of Ions in solution in which devided by two aspects one is the solution aspect and second one is ionic
Electrochemical Cells Chapter 12 FSc part 1.pptx
1) Electrolytic conduction involves the movement of ions through an electrolyte, either in molten or aqueous solution states. Ions form when ionic compounds dissolve or melt.
2) Electrochemical cells use redox reactions and can be either electrolytic cells or galvanic cells. Electrolytic cells use a power source to drive non-spontaneous reactions, while galvanic cells produce electricity from spontaneous reactions.
3) Key parts of electrolytic cells include an anode and cathode, with oxidation occurring at the anode and reduction at the cathode. During the electrolysis of molten salts, ions are produced which undergo reactions at the electrodes. In aqueous solutions, chlorine gas forms at
Electrolysis.pptx
This document discusses factors that determine which ions are discharged at the electrodes during electrolysis. For molten compounds containing one cation and one anion, the cation will be reduced at the cathode and the anion will be oxidized at the anode. For compounds in solution, the position of ions in the electrochemical series and concentration determine which ions are discharged. Ions higher in the anion series and lower in the metal series are preferentially discharged at the anode and cathode respectively. In dilute solutions, OH- and H+ ions are discharged but in concentrated solutions the ions from the compound may be discharged instead.
Hydrogen (hydrogen, water)
Hydrogen is the first element with one electron. It resembles alkali metals and halogens due to its ability to gain or lose electrons. Hydrogen forms covalent, ionic, and interstitial compounds called hydrides with other elements. Water has many unique properties due to hydrogen bonding between molecules. Hard water contains calcium and magnesium ions that can be removed by boiling, using limewater, or sodium carbonate to produce soft water suitable for household use.

Nursing management of the patient with Tonsillitis PPT
Prepared by Prof. Blessy Thomas MSc Nursing, FNCON, SPN. The tonsils are two small glands that sit on either side of the throat.
In young children, they help to fight germs and act as a barrier against infection.
Tonsils act as filters, trapping germs that could otherwise enter the airways and cause infection.
They also make antibodies to fight infection.
But sometimes, they get overwhelmed by bacteria or viruses.
This can make them swollen and inflamed.
Tonsillitis is an infection of the tonsils, two masses of tissue at the back of the throat.
Tonsillitis is inflammation of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side.
Tonsillitis is common, especially in children.
It can happen once in a while or come back again and again in a short period.Nursing management of Tonsillitis is important.
A comprehensive understanding of the operations for management of Tonsillitis and areas requiring special attention would be important.

- 3. 1. Electrolytic Properties • A substance (such as NaCl) whose aqueous solutions contain ions is called an electrolyte. A substance (such as C12H22O11) that does not form ions in solution is called a nonelectrolyte. • The different classifications of NaCl and C12H22O11 arise largely because NaCl is ionic, whereas C12H22O11 is molecular.
