While diluting an acid, why is it recommended that the acid should be added to water and not water to the acid?
Dissolving an acid in water is an exothermic reaction, it is always recommended that acid should be added to water, in this case heat produced is not sufficient to burn out, if we add acid to water then it is possible that because of the large amount of heat generated, the mixture splashes out and causes burns.
