Thermodynamic and Dynamic Modeling of the Boron Species in Aqueous Potassium Borate Solution.

ABSTRACT: The concentration of B(OH)₃, B(OH)₄ ^-, B₃O₃(OH)₄ ^-, and B₄O₅(OH)₄ ^2- in the solution and the solubilities in the system KCl-K₂SO₄-K₂B₄O₇-H₂O and its subsystems were calculated on the basis of the Pitzer model. The mole fraction of the four boron species is mainly affected by m(B) in the solution but less by m(Cl^-) and m(SO₄ ^2-). m(Cl^-) and m(SO₄ ^2-) mainly affect the solubility of K₂B₄O₅(OH)₄·2H₂O. The calculated solubilities in the system KCl-K_2</
