Ph of amphoteric salts
WebAmphoteric oxides are a curious group of oxides that can behave as both acidic and basic, depending on whether the other reactant is an acid or a base. In both cases salt and water are formed. Two of the most common amphoteric oxides are zinc oxide, ZnO and aluminum oxide, Al2O3. The hydroxides of both of these elements also behave amphoterically. WebA full calculation of the pH of amphoteric ion salts is complicated. To determine the H" concentration, we must take into account the acid and base equilibria, the autoionization of water, and the charge and material balance —five equations in all for the five unknown concentrations ( [H ], [OH ], [CO3 ], [HCO3], and [H2CO3]).
