Potentiometric determination of sodium concentrations in aqueous-ethanolic solutions.
The potentiometric behaviour of a sodium ion-selective glass electrode in aqueous ethanolic media was studied. The electrode was then used to determine sodium ion concentrations in aqueous ethanolic samples by standard-addition potentiometry.
