WebWe have seen that the concentrations of \text {H}_3\text {O}^+ H3O+ and \text {OH}^- OH− are equal in pure water, and both have a value of 10^ {-7}\text { M} 10−7 M at 25\,^\circ\text {C} 25∘C. When the concentrations of hydronium and hydroxide are equal, we say that the solution is neutral. WebAug 14, 2024 · In aqueous solutions, H_3O^+ is the strongest acid and OH^− is the strongest base that can exist in equilibrium with H_2O. The leveling effect applies to solutions of strong bases as well: In aqueous solution, any base stronger than OH− is leveled to the strength of OH− because OH− is the strongest base that can exist in equilibrium with water.
