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. WebHydrogen sulfide dissociates in water into H2S, HS- and S-. Only the un-ionized H 2 S is toxic because it readily passes through biological membranes. The dissociation of hydrogen sulfide in water: H 2 S <==> HS- + H+ <==> S 2 - + H+. The dissociation of hydrogen sulfide is strongly influenced by pH and to a lesser extent temperature and salinity.
