potassium borate formula ( K2B4O5(OH)4*2H2O ) is an ionic compound composed of potassium ions, aluminium ions, and borate ions. It exhibits nonlinear optical properties and can be used as a photoluminescent agent for the detection of biomolecules, viruses, and other organisms.
Potassium tetraborate is a crystalline, white, powdery granular substance with excellent buffering characteristics. It is commonly used as a boron tetraborate replacement for borax in chemical buffers, coating processes, and other industrial applications.
It is soluble in water and can be used as a saline solution for corrosion protection of metals. It is also an effective aqueous acidifier and can be used as a pH adjuster in electroplating procedures.
The potassium borate is soluble in both methylene chloride (HCl) and acetic acid at a concentration of 0.005 mol mL-1). It is a white crystalline hydrate with a high degree of solubility in water, and it has good dilution characteristics.
Borate salts and borate ions tend to form a monodentate contact ion pair (MCIP) with a K-B distance
The Pitzer electrolyte solution theory and Harvie-Weare (HW) equations are widely used to calculate the solubilities of the systems containing borate. However, the calculation of the systems containing potassium borate was not reported in the literature. Moreover, the Pitzer mixing parameters l between B(OH)3 and other ions were not included in the calculations.
