General description

Monobasic potassium phosphate crystals are colorless, soluble in water and hygroscopic in nature.Upon heating through 187°C, phase transition occurs in KH2PO4, crystal system changes from tetragonal to monoclinic, lattice parameters at 195°C are α=7.47Å, b =7.33Å, c =14.49Å, α=ß=90° and γ=92.2.[2]
