Abstract

Calcium & Magnesium soaps of caproic and caprylic acids were prepared and a cell was set up for the measurement of EMF of the cell containing referred 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 Critical Micelle Concentration of these soap solutions varies with increase in chain length of the fatty acids in the soap. The energetic studies of the system have been carried out from the electromotive force values of the cell containing soap solution to ascertain the chain length compatibility and agglomeration profile. 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. The effect of various organic additives on CMC values of referred soaps has also been studied by using electrometric method with the aid of ion selective electrode.
