(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.
Answer -
Now,
- The mixing of water to an acid is highly exothermic in nature.
- If water is added to an acid it produces a very large amount of heat. This can break the container and sometimes even causes burning as acids can heat up very quickly.
- So it is advised to add concentrated acid to water in a very slow manner.
So, the correct answer is (a)
