Because acid is hygroscopic. The water will bounce out. If you add water chances of accident is very high.

Mixing of water and acid is a highly exothermic process. When water is added to acid , due to small amount of water, evolved heat will change it to vapour and acid will spill out and may cause injury. So it is advised to mix acid to water and not water to acid

Because when will we pour water in acid then the acid will over flow it will be danger for us.

Rahul, If you are pouring acid in water, the energy released due to acid water interaction is absorbed by water which is present in larger amount as compared to acid. Now if you do it the other way , the energy in this case will be absorbed by the small amount of water you are adding. As a result that...

Rahul, If you are pouring acid in water, the energy released due to acid water interaction is absorbed by water which is present in larger amount as compared to acid. Now if you do it the other way , the energy in this case will be absorbed by the small amount of water you are adding. As a result that water will splash out of the vessel carrying along with it particles of acid. Therefore to avoid any causality we add acid to water. Hope this solves your doubt. read less

Water is not added to acid as it is an ex otherwise process in which so much heat is produced that splashing of acidic solution may occur, even container may break and can be fatal to the person.

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. (a) If you add water to acid, it forms extremely concentrated solution of acid initially. So much heat is released that the solution may...

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. (a) 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. (b) 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. read less

This is because adding water to concentrated solutions of acid may result in release of tremendous heat which may result in splashing of acid or other precarious results. Pouring acid in large amount of water result in diluted solution with very less heat release.

Because water is added on pour acid heat is produced but its heat absorbing by acid so it is cause of burn.
