Question

Sulphuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$ is a strong acid and is extremely useful both in the industry and in the laboratory. It forms two types of salts on reacting with a base. These are acid salts and normal salts. Care must be taken while diluting the acid with water. It is done by adding acid drop wise to water taken in a beaker and not water to the acid. Why does conc. H₂SO₄ form Blisters on the skin?

Answer 1

Concentrate H₂SO₄ solution forms blisters on the skin because:-

1. H₂SO₄ is a strong corrosive acid with dehydrating nature.
2. When this solution comes in contact with the skin it dehydrates the skin and causes damage to the cells and forms blisters.

Thus, conc. H₂SO₄ solution produces blisters on the skin.
