Abstract

Results of density and viscosity measurements for aqueous solutions of MgCl2 (0.5–3.5 mol L− 1) and MgCl2 + 10% NiCl2 (0.5–3.5 mol L− 1) at temperatures of 25, 60 and 90 °C show an almost linear increase in density with total concentration, while low nickel contents and temperature have comparatively small effects. Viscosities of MgCl2 solutions rise sharply at 25 °C but are significantly lower at 90 °C. The viscosity of 3–4 mol kg− 1 MgCl2 at 90 °C is similar to water at 25 °C. Nickel has no significant effect on the viscosity of these solutions. Results of heat capacity measurements for aqueous solutions of MgCl2 (0.5–3.5 mol L− 1) and MgCl2 + 10% NiCl2 (0.5–3.5 mol L− 1) at temperatures of 60 and 90 °C show that the heat capacities of these solution decrease significantly with total concentration, while the effects of low nickel contents and temperature are again comparatively small.
