چکیده انگلیسی
Molar volume, viscosity and conductance of lithium chloride (LiCl), sodium chloride (NaCl) and potassium chloride (KCl) in 0.01 m aqueous ascorbic acid have been calculated from density, viscosity and conductance data at temperatures 303.15, 308.15, 313.15 and 318.15 K. The solute-solvent interactions for LiCl, NaCl and KCl have been inferred from Ïvo, B-coefficient of Jones-Dole equation and Îmo values. The structure making/breaking behavior of LiCl, NaCl and KCl is inferred from the sign of [â2Ïvo/âT2]p, dB/dT and temperature coefficient of Walden product i.e. d(Îmoηo)/dT values. It has been found from molar volume, viscosity and conductance studies that LiCl, NaCl and KCl behaves as structure-breaker in 0.01 m aqueous ascorbic acid solution. The energy of activation for LiCl, NaCl and KCl is calculated from conductance and viscosity data and it has found that EÎ is less than Eη.
