$Cl^{-}$ is a Lewis acid

Vedclass · Answer

(C) $Cl^{-}$ is a Lewis base,not a Lewis acid,because its octet is complete and it has a lone pair of electrons to donate.For $1.0 	imes 10^{-8} \ M \ HCl$,the contribution of $H^{+}$ from water must be considered,resulting in a $pH$ slightly less than $7$ (approx $6.98$).The ionic product of water $(K_w)$ at $25^{\circ} C$ is $1.0 	imes 10^{-14} \ mol^2 \ L^{-2}$.$AlCl_{3}$ acts as a Lewis acid due to an incomplete octet,which is not explained by the Bronsted-Lowry theory.
