Which of the following phenomena occur, when a small amount of acid is added to water?
(i) Ionisation (ii) Neutralisation
(iii) Dilution (iv) Salt formation
(A) (i) and (ii)
(B) (i) and (iii)
(C) (ii) and (iii)
(D) (ii) and (iv)
When a small amount of acid is added to water, it forms a dilute solution and it also ionizes i.e. it breaks down into its constituent ions.
Neutralization and salt formation take place only when both acid and base are present .
So, the correct option is (b) (i) amd (iii)
