Question

Give me full topic Acid and bases.
Please give me fast please
Give me verify answer.

Answer 1

Answer:

An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. When these substances chemically react with acids, they yield salts. Bases are known to turn red litmus blue

Answer 2

Answer:

An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste.

Explanation:

In 1884, the Swedish chemist Svante Arrhenius proposed two specific classifications of compounds; acids and bases. When dissolved in an aqueous solution, certain ions were released into the solution. An Arrhenius acid is a compound that increases the concentration of H+ ions that are present when added to water. These H+ ions form the hydronium ion (H3O+) when they combine with water molecules. This process is represented in a chemical equation by adding H2O to the reactants side.

HCl(aq)→H+(aq)+Cl−(aq)(1)

In this reaction, hydrochloric acid ( HCl ) dissociates completely into hydrogen (H+) and chlorine (Cl-) ions when dissolved in water, thereby releasing H+ ions into solution. Formation of the hydronium ion equation:

HCl(aq)+H2O(l)→H3O+(aq)+Cl−(aq)(2)

The Arrhenius theory, which is the simplest and least general description of acids and bases, includes acids such as HClO4 and HBr and bases such as NaOH or Mg(OH)2 . For example the complete dissociation of HBr gas into water results generates free H3O+ ions.

HBr(g)+H2O(l)→H3O+(aq)+Br−(aq)(3)

This theory successfully describes how acids and bases react with each other to make water and salts. However, it does not explain why some substances that do not contain hydroxide ions, such as F− and NO−2 , can make basic solutions in water. The Brønsted-Lowry definition of acids and bases addresses this problem.

An Arrhenius base is a compound that increases the concentration of OH- ions that are present when added to water. The dissociation is represented by the following equation:

NaOH(aq)→Na+(aq)+OH−(aq)(4)

In this reaction, sodium hydroxide (NaOH) disassociates into sodium (Na+) and hydroxide (OH-) ions when dissolved in water, thereby releasing OH- ions into solution.
