Question

while diluting an acid why it is recommended that the acid should be added to water not water to the acid

Answer 1

While diluting an acid , acid should be added to water as if water is added to acid it may splash and harm the person and since it is a highly exothermic reaction the glass may break. Thus acid is added to water and the mixture is stirred continuously.

Answer 2

Explanation:

Since the process of dissolving an acid in water is exothermic, it is always recommended that acid should be added to water. If it is done the other way, then it is possible that because of the large amount of heat generated, the mixture splashes out and causes burns.
