This happens with strong acids and bases. Strong means the acid almost complete dissociates into ions; e.g. HCl to H+ and Cl−. When the dissociation occurs, it releases a great deal of heat (i.e. exothermic) because of the subsequent hydration of H+ to H3O+, as the other comments have indicated. The reason you add acid to water is that if you add water to acid, the first drop of water reacts immediately, and the heat might be high enough to boil the water instantly, which could spray acid out of the container.

Hello!❤️
Because the reaction between an acid and water is very exothermic. It may cause breakage to the test tube or beaker that you'll use!
It's preferable to add acid in water with constant stirring!
Hopefully the answer is helpful!❤️
