Solution
When a small amount of acid is added to water, the following phenomena occur:
(i) Ionisation: This is the process where the acid (a covalent compound) breaks down into its constituent ions. For example, when hydrochloric acid (HCl) is added to water, it ionises to form hydrogen ions (H+) and chloride ions (Cl-).
(iii) Dilution: This is the process of reducing the concentration of the acid by adding it to water. The more water you add, the more diluted the acid becomes.
So, the correct answer is (b) (i) and (iii).
