Professor PC Thomas Classes · Answer

(d):During the dilution of a strong concentrated acid like $\mathrm{HNO}_{3}$, always add acid to water and not the water to acid. The dissociation of an acid in water is a highly exothermic process as acid has strong affinity for water. Large amount of heat is produced on mixing the acid with water. Hence, the acid is always diluted by adding the acid to water slowly and with constant stirring.\
