Hi !
(a) The method to be followed is that , acid (sulphuric acid) should be added to water , and not vice versa. That is , water should NEVER be added to acid. This is because water reacts very vigorously when added to acid, and releases a large amount of heat , and splashes the concentrated acid( sulphuric acid) out of the container. Hence, it is COMPULSORY to add acid to water , as only a little amount of heat is released,and also the reaction won't be that violent.
(b) The process of adding acid to water , is called dilution of acids.

(i) When strong acids are mixed with water a large amount of heat is released. Addition of more acid releases more heat. If we add water to acid, it forms an extremely concentrated solution of acid initially such that solution may boil very violently releasing heat, splashing concentrated acid out of the container. If you add acid to water, the solution that forms is very dilute and a very little amount of heat is released with out involving any violent reactions. So Always Add Acid to water, and never the reverse. Hence we should add 5 ml of sulphuric acid to 10 ml of water.
(ii) Dilution of the add...
