Monopotassium phosphite is an inorganic compound with the formula KH2PO3. A compositionally related compound has the formula H3PO3.2(KH2PO3). Both are white solids that consist of salts of the phosphite anion H2PO3, the conjugate base of phosphorous acid.[1] These materials have been used in some fertilizers.
