Question

Assertion (A): In the Contact Process SO₃ gas is not directly dissolved in water to obtain sulphuric acid.

Reason (R): Dense fog or misty droplets of sulphuric acid are formed which is difficult to condense.

Options

• Both (A) and (R) are true, and (R) is the correct explanation of (A).

• Both (A) and (R) are true, and (R) is not the correct explanation of (A).

• (A) is true but (R) is false.

• (A) is false but (R) is true.

Answer 1

Both (A) and (R) are true, and (R) is the correct explanation of (A).

Explanation:

In the Contact method, sulphur trioxide gas (SO₃) is not immediately dissolved in water to produce sulphuric acid, as this results in the formation of dense fog or misty droplets of sulphuric acid, which can be difficult to condense.
