Abstract
Abstract The nature of chromotropic acid as a colloidal electrolyte has been established from electrical conductance studies. The curve obtained by plotting the square root of concentration and molar conductance of the reagent solution is not linear and resembles that of a colloidal electrolyte. The temperature coefficient per degree centigrade per hundred units of conductance at 35°C is between 1.5 and 1.7. The temperature of zero conductance, determined by extrapolation, is −20.0°C.
