Question

2. Whey it is recommended that during
dilution always add concentrated acid to
water not water to acid?​

Answer 1

Answer:

So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container and all this because the reaction is exothermic. ... So it is always safer to add acid to water, and not water to acid.

Answer 2

it is recommended so because if we add water to concentrated acid,it may cause splashes and breaking of the beaker because of intense local heating.

so, we should add acid to water to dilute it slowly while stirring
