Vedclass · Answer

(C) For a very dilute solution of $HCl$ with concentration $10^{-8} \ M$,the contribution of $H^+$ ions from the auto-ionization of water cannot be neglected.Total $[H^+] = [H^+]_{HCl} + [H^+]_{H_2O}$.Since $[H^+]_{HCl} = 10^{-8} \ M$ and $[H^+]_{H_2O} \approx 10^{-7} \ M$,the total $[H^+]$ will be slightly greater than $10^{-7} \ M$.Therefore,$pH = -\log[H^+] Thus,the $pH$ of a $10^{-8} \ M \ HCl$ solution is slightly less than $7$.
