Question

Assertion (A): It is advised that while diluting an acid one should add water to acid and not acid to water keeping the solution continuously stirred.

Reason (R): The process of dissolving an acid into water is highly exothermic.

Options

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

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

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Assertion (A) is false, but Reason (R) is true.

Explanation:

It is crucial to add the acid to the water before adding the water to the mixture of acid and water. This is because acid and water react vigorously exothermically, producing heat and occasionally boiling the liquid.
