Abstract

Calcium soap of caprylic acid was prepared and a cell was set up for the measurement of EMF of the cell having soap solutions in methanol water solvent system with the aid of Ion-Selective Electrode. The Critical Micelle Concentration of soap solutions was determined by plotting the electromotive force of the cell against soap concentration. The effect of hydroxy additives on CMC values of referred soap solution has been studied by graphical method. Free energy change (DG) for given cell reaction was determine. 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.
