Steady-state electrolysis of a solution of nonamphotheric compounds

The problem of stationary electrolysis of a solution of nonamphotheric compounds (acids or bases) is considered. The analysis is performed by taking into account the mobility dependence on pH. The properties of such a system are also compared with the ones pertaining to the solution of an amphoteric substance. It is anticipated that steady-state electrolysis of free acids and bases, in a convection-free system, might be useful for creating narrow pH gradients in rather acidic and alkaline milieus, which might be adopted for focusing without resorting to conventional carrier ampholytes or immobilized pH gradients.
