Question

For diluting sulphuric acid ; the acid should be added to water instead of water being added to acid ? Justify :​

Answer 1

Answer:

Adding water to acid is a highly exothermic process.

If this would happen the beaker may break and the solution may splash out causing injuries.

That's what it is always advised to add acid to water and not water to acid with constant stirring.

Hope it helps.

Answer 2

Answer:

Dilution of concentrated acid is an exothermic process. If water is added to a concentrated acid, the heat generated may cause the mixture to splash out and cause burns. When the acid is added to water slowly with constant stirring, the mixture will not splash out.
