Question

For a dilution of acid, acid is added into water and not water into acid. Why

Answer 1

Answer:

So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container! If you add acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize and spatter it. So Always Add Acid to water, and never the reverse.

Answer 2

Explanation:

for dilution of acid acid is added into water not water into acid because if we add water into acid it forms an extremely concentrated solution of acid initially. So much heat is released that the solution may boil very violently splashing concentrated acid out of the container and all this because solution is exothermic.
