- •
Solubility of RbCl(cr) and CsCl(cr) in pure water were determined at subzero temperatures.
- •
Specific heat capacity of RbCl(aq) and CsCl(aq) solutions were determined at 298.15 K and concentration to near saturation.
- •
Temperature dependent thermodynamic models for RbCl + H2O and CsCl + H2O binary systems were developed.
- •
The models can represent all the properties of the systems simultaneously with one set parameters.
- •
The models have an advantage especially at subzero temperatures.
