Question

Why acid must be added to water and not vice versa brainly?

Answer 1

Answer:

Explanation:

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, this may harm you while doing the experiment, 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

Explanation:

water is never poured in Acid to dilute it as large amount of heat is evolved which changes board water into steam . The steam so form causes spurting of acid which can cause burn injuries , so dilution is done by pouring acid on a given amount of water in a controlled manner by continuous stiring, else acid being heavier will settle down. The evolved heat is dissipated in the water itself and hence the spurting of acid is minimized.
