What is the correct method of diluting an acid?

Dilution is the process of adding water.

When water is added to the acid, a huge amount of heat is released and this heat even boils the acid and can cause a splash of acid over the person holding it.

Thus, it is a highly exothermic reaction. Due to this reason, the correct way of adding water to acid is to add a small amount of acid to the water. In this case, only a small amount of heat is produced.
