Abstract

Abstract By electrical conductance studies it has been found that ammonium purpurate behaves as a colloidal electrolyte and does not obey Beer’s law in concentrated solutions. The curve between the square root of the concentration and the molar conductance is not linear and resembles that of a colloidal electrolyte. The temperature of zero conductance has also been determined to be −20°C. The temperature coefficient per degree centigrade per hundred of the conductance at 35°C ranges between 0.86 and 1.65.
