ANSWER (C) Upvote • 1 Downvote Add comment Report Robert S. answered • 12/12/20 Tutor 4.9 (112) WebbpH = -log [H+] HCl is a strong acid, completely dissociated in water. Therefore, a concentration of HCl = 2*10^-8 M H2O dissociates (H2O = H+ + OH-, Ka = ~10^-14) and therefore, water contributes 10^-7 M H+. Normally, this is small compared to the concentration of the acid and is not a consideration.
