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.
