A call from the mayor
If water gets into concentrated acid, it causes a lot of heat (the dissolution process is exothermic), and the boiling liquid flies everywhere and causes a lot of damage. The right is to add acid to water little by little (water has a higher heat capacity) and stir long and thoroughly.
Well, these rules rather apply to sulfuric acid specifically. The heat capacity is not much different, but the density is. If you splash water, it stays on the surface, where it is quite capable of boiling. On the contrary, the acid passes through the entire thickness, dissolving and cooling down.
