Question

Assertion (A): Sodium sulphate is the normal salt.

Reason (R): Sodium sulphate is formed by the partial replacement of hydrogen of acid.

पर्याय

• If both A and R are true, and R is the correct explanation of A.

• If both A and R are true, but R is not the correct explanation of A.

• If A is true, but R is false.

• If both A and R are false.

Answer 1

If A is true, but R is false.

Explanation:

The assertion is true because sodium sulphate (Na₂SO₄) is a normal salt formed by the complete neutralisation of sulphuric acid. The reason is false because partial replacement of hydrogen atoms yields an acid salt like sodium bisulphate (NaHSO₄), not a normal salt. Normal salts contain no replaceable hydrogen atoms left in their formula.
