Question

Sulphuric acid is used to prepare more volatile acids from their corresponding salts due to its ______.

Options

• strong acidic nature

• low volatility

• strong affinity for water

• ability to act as a dehydrating agent

Answer 1

Sulphuric acid is used to prepare more volatile acids from their corresponding salts due to its low volatility.

Explanation:

Sulphuric acid (\[\ce{H2SO4}\]) is used to prepare more volatile acids (e.g., \[\ce{HCl}\]) from their salts because of their low volatility. This allows it to remain in the reaction mixture while the more volatile acid is released as a gas without being lost or evaporated.
