Relative viscosities for the solutions of lithium chloride in 2, 4 and 6 wt. % lactose at different temperatures i.e. 303.15K, 308.15K, 313.5K and 318.15K have been determined. The data have been evaluated using the Jones–Dole equation and transition state theory of relative viscosity of electrolytic solutions and the obtained parameters have been interpreted in terms of solute–solute and solute–solvent interactions. The activation parameters of viscous flow have been obtained which depicts the mechanism of viscous flow. Lithium chloride behaves as structure breaker in 2, 4 and 6 wt. % lactose at different temperatures i.e. 303.15K, 308.15K, 313.5K and 318.15K.
