Why is it considered safe to add acid slowly into water during dilution?

Answer and explanation

Correct answer: Heat spreads gradually and splashing is reduced

Dilution of a concentrated acid is highly exothermic because hydration of its ions releases considerable heat. Adding acid slowly to a larger quantity of water allows the heat to disperse gradually and reduces the chance of local boiling, splashing, and burns. Therefore option A is correct. The acid does dissolve in water, is not made solid, and dilution does not itself neutralise it.
