Question

b. While diluting an acid ,why it is advised to add the acid to water and
not vice versa?​

Answer 1

Explanation:

Adding more acid releases more heat. If you add water to acid, you form 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! ... So Always Add Acid to water, and never the reverse.

Answer 2

Answer:

the dilution of acid and water is highly exothermic ones

it is advised to mixed acid into water but not vice versa

because if we mix water into acid then the heat will gradually evolve at once . some of this water is converted to form steam due to the large amount of heat this steam will come out from the beaker which can splash our face , cloth,acid burn
