Potassium Phosphite Solution
Synonyms: Mixture of monopotassium phosphite and dipotassium phosphite wate solution
CAS No.: KH2PO3: 13977-65-6 K2H2PO3: 13492-26-7
Molecular Weight: KH2PO3:120.078 K2H2PO3: 158.18
Molecular Formula: Mixture of KH2PO3, K2HPO3 and water
Potassium phosphite solution can be obtained by neutralization reaction between phosphorous acid (H3PO3) and potassium hydroxide (substitution is potassium carbonate, which the reaction will give out a lot of carbon dioxide gas)
1) Potassium phosphite solution is used as foliar fertilizer and water-soluble fertilizer.
2) Potassium phosphite is used as fungicide to control Oomycetes (esp. Phytophthora sp), similar to fosetyl aluminium (Aliette).
