A one-parameter equation for predicting densities of aqueous mixed electrolytes

164-166A new one-parameter equation has been proposed for predicting the densities of aqueous mixed electrolytes. The derivation of the equation is based on the characterization of overall non-ideality in such solutions. The parameter of equation can be correlated well with the ionic interactions and can be supported by corresponding heats of mixing and excess Gibbs free energy of mixing data. The predictions for the densities with the use of the proposed equation are excellent
