Explanation:

Chemical Properties of Acid and Bases

1. Reactions of Acids and Bases with Metals

When a metal reacts with an acid, it generally displaces hydrogen from the acids. This leads to the evolution of hydrogen gas. The metals combine with remaining part of acids to form a salt. For example reaction of sulphuric acid with zinc.

H2SO4 + Zn → ZnSO4 + H2

Alkalis (bases that are soluble in water) react with the metal to produce salt and hydrogen gas. For example reaction of zinc with sodium hydroxide.

2 NaOH + Zn → Na2ZnO2 + H2

2. The Reaction of Metal Carbonates/Metal Bicarbonates with Acids

Metal carbonates/metal bicarbonates react with acids to produce salt, carbon dioxide and water. For example the reaction of sodium carbonate/sodium bicarbonate with hydrochloric acid.

Na2CO3 + HCl (aq) → 2NaCl (aq) + H2O(l) + CO2

3. The Reaction of Metal Oxide with Acids

Metal oxides react with acids to produce salt and water. For example reaction of copper oxide and dilute hydrochloric acid.

CuO + 2HCl → CuCl2 + H2

4. The Reaction of Non-metal Oxide with Bases

Non-metal oxides react with bases to produce salt and water. For example the reaction of carbon dioxide and lime water (calcium hydroxide)

CO2 + Ca (OH)2 → CaCO3 + H2O

5. The Reaction between Acids and Bases

Acids react with bases to produce salt and water. The reaction between acids and bases to give salts is known as neutralization reactions. For example the reaction of sodium hydroxide with hydrochloric acid.

NaOH + HCl → NaCl + H2O

Neutralization of Acid and Base

The reaction between an acid and a base invariably gives salt and water and is called neutralization. In a neutralization reaction, one H+ ion of acid is neutralized by one OH– ion is base. When all the H+ ions in the acidic solution are neutralized by the same number of OH– ions of basic solution, it is called complete neutralization. The relative amounts of acid and base required for complete neutralization depends upon the total number of H+ and OH– ions produced by the respective acid and base.
