Why is water not added to concentrated $H_{2} S O_{4}$ in order to dilute it ?

Open in App

Solution

Water is not added to concentrated acid since it is an exothermic reaction. If water is
added to the acid, there is a sudden increase in temperature and the acid being in
bulk tends to spurt out with serious consequences.
