उत्तर
Sulphuric acid is called the King of Chemicals because there is no other manufactured compound that is used by such a large number of key industries.
Some uses of sulphuric acid are:
- It is used as a laboratory reagent.
- Metallurgy plays a significant role in the manufacture of explosives.
- In storage batteries.
- It is used in dyes and drugs.
- In the refining of petroleum.
- In fertilisers.
- To prepare other acids, etc.
