EMF of the cell containing calcium caproate soaps solution in methanol-water solvent system waas measured with the aid of ion-selective electrode. The Critical Micelle Concentration of soap solutions was determined by graphical method. The effect of amide additives on CMC values of referred soap solution has been studied by using electrometric method with the aid of ion selective electrode. The values of free energy change are negative indicating the spontaneity of cell reaction and decreases with increasing soap concentration while increases with the increase methanol concentration in solvent mixture.
