WebAnswer (1 of 6): Water is an acid. I'm an organic chemist, and we often work with things toward which water is a pretty strong acid. Water is not as acidic as HF or H2S. HF is more acidic than water because F is more electronegative than O; therefore F^- is a weaker base than OH^-. H_2S is mor... WebJan 24, 2016 · Please note that H2O dissociates partially to form H3O+ and OH- and that this process reaches equilibrium with finally the ionic product: [H+][OH-]=10^-14. If an acid is added to water. H+ increases and hence by the Law of Mass Action the equilibrium is pushed to the left and the concentration of OH- decreases.
