How will you protect yourself from the heat generated while diluting a concentrated acid?
(A) By adding acid to water with constant stirring.
(B) By adding water to acid with constant stirring.
(C) By adding water to acid followed by base.
(D) By adding base to acid with constant stirring.
- The mixing of water to an acid is highly exothermic in nature.

- So it is advised to add concentrated acid to water in a very slow manner.
So, the correct answer is (a)
