Question

Assertion (A): All acids form hydronium ions when dissolved in water.

Reason (R): Every acid has hydrogen as the necessary element.

Options

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

• Both A and R are true but 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:

Both statements are true. Acids contain ionisable hydrogen, which combines with water to form hydronium ions; thus, the reason explains the assertion.
