Question

Why we should not put acid on water but we put water on acid

Answer 1

Heya,

Mixing of water and acid is a highly exothermic process.

When water is added to acid , due to small amount of water, evolved heat will change it to vapour and acid will spill out and may cause injury.

So,it is advised to mix acid to water and not water to acid.

Answer 2

This is because the reaction between acid and water is highly exothermic and so produces lot of heat. ... On the other hand, when we add acid to water, it is like adding a concentrated solution to water in small amounts. So comparatively lesser amount of heat is released.It's vital that you do it that way round with concentrated sulfuric acid, because the reaction is strongly exothermic. If you add water to the acid it will boil violently and spit concentrated acid in all directions. ... With other mineral acids this is not so essential, but it's still extremely good practice. When an acid is diluted by adding water to it the concentration of H+(aq) ions decreases. If the concentration of H+(aq) ions decreases the pH will increase. pH is a measure of H+(aq) ion concentration.If you add water to 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 the reaction is exothermic. ... So it is always safer to add acid to water, and not water to acid.
