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

Answer and explanation

Correct answer: Because heat is released and splashing is reduced

Dilution of a concentrated acid is highly exothermic: heat is released when acid particles become solvated by water. Adding acid slowly to a larger quantity of water allows the released heat to disperse through the water and permits controlled stirring, reducing the chance of sudden boiling and splashing. Adding a small amount of water to concentrated acid can create intense local heating and dangerous splashes. The acid does not freeze or become a base, so option A is correct.
