Vedclass · Answer

(A) $HCl$ is a strong acid that dissociates completely in water according to the reaction: $HCl \rightarrow H^{+} + Cl^{-}$.Since it is a strong electrolyte,the concentration of $H^{+}$ ions is equal to the concentration of the acid,which is $0.1 \ M$.$NH_4Cl$ is a salt of a weak base and strong acid,which undergoes hydrolysis to produce a small amount of $H^{+}$ ions.$NaHCO_3$ and $Na_2CO_3$ are basic salts that produce $OH^{-}$ ions in solution,thereby decreasing the concentration of $H^{+}$ ions.Therefore,the $0.1 \ M \ HCl$ solution contains the maximum number of $H^{+}$ ions.

Which solution contains the maximum number of $H^{+}$ ions?
