Question

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

Answer 1

Answer:

Dilution of concentrated acid is an exothermic process. If water is added to a concentrated acid, the heat generated may cause the mixture to splash out and cause burns. When the acid is added to water slowly with constant stirring, the mixture will not splash out.

Answer 2

Answers

The process of dissovling an acid or base in water is a highly exothermic. The acid must always be added slowly to water with constant stirring. If water is added to a concentrated acid, the heat generated may cause the mixture to splash out and cause burns. The glass container may also break due to excessive local heating.
