Question

While using an acid, why it is recommended that the acid should be added to water and not water to the acid?

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.
