Vedclass · Answer

(A) Hydrochloric acid $(HCl)$ is a strong acid that undergoes complete dissociation in an aqueous solution.When $HCl$ is dissolved in water,it reacts with water molecules to form hydronium ions $(H_{3}O^{+})$ and chloride ions $(Cl^{-})$.The dissociation reaction is represented as: $HCl(aq) + H_{2}O(l) \rightarrow H_{3}O^{+}(aq) + Cl^{-}(aq)$.Since it is a strong acid,almost all $HCl$ molecules dissociate into ions,leaving negligible amounts of unionised $HCl$ in a dilute solution.Therefore,the primary species present in the solution are $H_{3}O^{+}$ and $Cl^{-}$.
