Vedclass · Answer

(D) When a small amount of acid is added to water,the following processes occur:$1$. Ionisation: The acid molecules dissociate into their respective ions (e.g.,$HCl \rightarrow H^+ + Cl^-$). This is the process of ionisation.$2$. Dilution: Adding water to an acid or adding a small amount of acid to a large volume of water decreases the concentration of $H_3O^+$ ions per unit volume,which is known as dilution.Therefore,both ionisation and dilution occur.
