TO STUDY THE THERMODYNAMIC PARAMETERS OF SUBSTITUTED THIOCARBAMIDOPHENOL IN 60% ETHANOL WATER MIXTURE

Recently in the laboratory conductometric investigation of 2-methyl thiocarbamidophenol (L2) have been carried out at different concentration of solute in 60% ethanol-water mixture at constant temperature. G, k, ? values are determined. The thermodynamic parameters ΔH, ΔG and ΔS for the ion pair formation determine from the value of ion association constant at different temperature i.e. 298.15K and 303.15 K. This measurement revealed that solvent-solvent, solute-solvent and solute-solute interaction and the effects of various substituents. Key Words: Substituted thiocarbamidophenol, ion association constant, thermodynamic parameters.
