Vedclass · Answer

(A) Ammonia $(NH_3)$ is a weak base that reacts with water as follows:$NH_3(aq) + H_2O(l) \rightleftharpoons NH_4^+(aq) + OH^-(aq)$In this reaction,$NH_3$ accepts a proton from water to form the ammonium ion $(NH_4^+)$ and releases hydroxide ions $(OH^-)$.The increase in the concentration of $OH^-$ ions makes the solution basic,which leads to a decrease in the concentration of $H_3O^+$ ions due to the ionic product of water $(K_w = [H_3O^+][OH^-])$.Therefore,the $OH^-$ ion is responsible for the change.

When ammonia is added to water,which of the following ions is responsible for the increase in its basicity (or decrease in $H_3O^+$ concentration)?
