Treatment of the electrodeposition of alkyl sulfate salts of viologen radical cations as an equilibrium process governed by a solubility product

The methyl viologen radical cation forms a deposit on the electrode surface in the presence of long-chain n-alkyl sulfates. It is shown that during growth of the deposit, the surface conentrations of the radical cation and alkyl sulfate anion remain close to the equilibrium values dictated by a solu...

Zusammenfassung:The methyl viologen radical cation forms a deposit on the electrode surface in the presence of long-chain n-alkyl sulfates. It is shown that during growth of the deposit, the surface conentrations of the radical cation and alkyl sulfate anion remain close to the equilibrium values dictated by a solubility product constant.
