Molar volume, viscosity and conductance studies of some alkali metal chlorides in aqueous ascorbic acid

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 ϕvo, B-coefficient of Jones-Dole equation and Λmo values. The structure making/breaking behavior of LiCl, NaCl and KCl is inferred from the sign of [∂2ϕvo/∂T2]p, dB/dT and temperature coefficient of Walden product i.e. d(Λmoηo)/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 EΛ is less than Eη.
