Question

write any three uses of acids and bases​

Answer 1

Answer:

ACID: 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.

BASES:

• Sodium hydroxide is used in the manufacture of soap, paper, and the synthetic fiber rayon.
• Calcium hydroxide (slaked lime) is used in the manufacture of bleaching powder.
• Calcium hydroxide is also used to clean the sulfur dioxide, which is caused by the exhaust, that is found in power plants and factories.

Uses of Acids

Uses of Acids

1. Hydrochloric Acid (HCl)

Dilute hydrochloric acid is used in various industries that use heating applications. It is applied to remove deposits from the inside of the boilers.

Hydrochloric acid is also used for cleaning sinks and sanitary ware.

2. Sulphuric Acid (H2SO4)

Sulphuric acid is such an important industrial chemical that it is called the king of chemicals. Some of its major uses are as follows:

Sulphuric acid is used in car batteries.

It is used in the manufacture of paints, drugs, dyes, and to produce fertilizers.

3. Nitric Acid (HNO3)

It is used by goldsmiths for cleaning gold and silver ornaments.

It is also used for the production of fertilizers such as ammonium nitrate.

4. Acetic Acid (CH3COOH)

Acetic acid is used directly to enhance the flavour of food. In fact, we commonly know acetic acid as vinegar.

It is also used as a cleansing agent in products meant for cleaning windows, floors, utensils, etc.

It also helps to remove stains on woodwork such as furniture and carpets.

Acetic acid is used as a preservative in pickles, etc. Most microorganisms cannot live in an acidic environment. An acidic environment either slows down their activities or can also kill them. This is why you will find vinegar in many commonly packaged food items such as pickles, sauce, ketchups, etc.

The following table shows the uses of some organic and inorganic acids.

USE OF BASES

Sodium hydroxide is used in the manufacture of soap, paper, and the synthetic fiber rayon.

Calcium hydroxide (slaked lime) is used in the manufacture of bleaching powder.

Calcium hydroxide is also used to clean the sulfur dioxide, which is caused by the exhaust, that is found in power plants and factories.
