The Arrhenius acid-base theory is suitable for explaining the acidic or basic properties of substances in water or other solvents.

Vedclass · Answer

(A) The Arrhenius theory defines acids as substances that increase the concentration of $H^+$ ions in water and bases as substances that increase the concentration of $OH^-$ ions in water.Statement $A$ is incorrect because the Arrhenius theory is strictly limited to aqueous solutions and cannot explain acidic or basic properties in non-aqueous solvents.Statement $B$ is correct because $AlCl_3$ is a Lewis acid,not an Arrhenius acid.Statement $C$ is correct because $Na_2CO_3$ is a salt of a strong base $(NaOH)$ and a weak acid $(H_2CO_3)$,making its solution alkaline due to hydrolysis,even though it does not contain $OH^-$ ions in its solid state.Statement $D$ is correct because $CO_2$ reacts with water to form $H_2CO_3$,which dissociates to provide $H^+$ ions,but $CO_2$ itself does not contain $H^+$ ions.
