Question

For diluting an acid, the acid should be poured carefully in water and not the reverse. Why

Answer 1

It is because diluting an acid is a very vigorous and exothermic reaction. It produces a lot of heat if poured directly. That's why acids should be poured in water with continuous stirring, not the reverse.

Answer 2

Answer:

The reaction of acid and water is an exothermic reaction since a lot of heat is liberated during the reaction. This heat changes some water to steam explosively which can splash the acid on our face or clothes and cause acid burns.

While diluting an acid, it is preferred that the acid is added to water rather than the water being added to the acid

Since adding water to a concentrated acid releases a large amount of heat, which can cause an explosion and acid burns on the skin, clothing, and other body parts.

As a result, adding acid to water is safe, but adding water to acid is not.
