A large amount of heat is released when strong acids like Sulphuric acid,HCl are. mixed with water.First,adding more acid. releases more heat,as it is exothermic.

                     If you add water  to acid  it                        forms extremely concentrated solution of.                        acid   initially.   So much heat is released.                            that the solution may boil very violently,                            splashing concentrated acid out of the                     container and all this because acid is                    

exothermic and corrosive.

     On the other hand, adding acid to                             water, the solution   that forms is. very                             dilute.  and the small.   amount of heat.                        released is not enough to vaporize and.                         spatter it.   So it is always  safe to  add.                               Acid to water, and  never the reverse. 

I hope you understand.

A large amount of heat is released when strong acids like sulfuric acid and HCl are mixed with water. First, adding more acid releases more heat, as it is exothermic.

If you add water to acid it forms an extremely concentrated solution of acid initially. So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container and all this because the reaction is exothermic.

On the other hand, adding acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize it. So it is always safer to add acid to water, and not water to acid.
