Question

Give any three examples each of acids and bases. Also mention any two uses of each of them.​

Answer 1

Answer: Example of Acid:

Sulfuric acid [H2SO4], Hydrochloric acid [HCl], Acetic acid [CH3COOH].

Example of Base:

Sodium hydroxide [NaOH], milk of magnesia [Mg(OH)2], calcium hydroxide [Ca(OH)2].

Uses of Acid:

• Vinegar, a diluted solution of acetic acid, has various household applications. It is primarily used as a food preservative.

• Citric acid is an integral part of lemon juice and orange juice. It can also be used in the preservation of food.

• Sulfuric acid is widely used in batteries. The batteries used to start the engines of automobiles commonly contain this acid.

• The industrial production of explosives, dyes, paints, and fertilizers involves the use of sulfuric acid and nitric acid.

• Phosphoric acid is a key ingredient in many soft drinks.

Uses of Base:

• The manufacturing of soap and paper involves the use of sodium hydroxide. NaOH is also used in the manufacture of rayon.

• Ca(OH)2, also known as slaked lime or calcium hydroxide, is used to manufacture bleaching powder.

• Dry mixes used in painting or decoration are made with the help of calcium hydroxide.

• Magnesium hydroxide, also known as milk of magnesia, is commonly used as a laxative. It also reduces any excess acidity in the human stomach and is, therefore, used as an antacid.

• Ammonium hydroxide is a very important reagent used in laboratories.

• Any excess acidity in soils can be neutralized by employing slaked lime.
