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. Webb18 year old girls with amazingly tight young and fresh bodies first time video. 8:04. 100%.
