The used potassium salts affect solubility of CaHPO4.2H2O, Ca3(PO4)2 and Ca(H2PO4)2.H2O. Changes of solubility depend on concentration and kind of anion in potassium salt. In the presence of KCl, KNO3 and K2SO4 solubility of CaHPO4.2H2O increases most whereas solubility of Ca3(PO4)2 slightly decreases. Solubility of Ca(H2PO4)2.H2O increases to a very small degree in the presence of KCl and K2SO4 and decreases in the presence of KNO3
