The solubility isotherms for the ternary system Li₂SO₄鈥揗gSO₄鈥揌₂O and the quaternary system Li₂SO₄鈥揔₂SO₄鈥揗gSO₄鈥揌₂O at T = 273.15 K were determined by the isothermal equilibrium method. A Pitzer鈥揝imonson鈥揅legg (PSC) model was used to simulate the properties of the binary and ternary systems of the quaternary title system. The binary model parameters were fitted against selected reliable experimental data of water activity. The mixture model parameters were obtained by fitting them to the ternary solubility isotherms taken from the literature and determined in this work. The solubility isotherms of the quaternary title system were predicted by the PSC model and compared with the experimental results in this work. The excellent agreement between the predicted and experimental results indicates that the experimental results obtained in this work are reliable.
