| [Hazard]
Moderate fire risk, may explode if ground
with chlorates, nitrates, or other strong oxidizing
agents.
| [Production Methods]
Potassium hypophosphite, KH2PO2, white solid, soluble, formed (1) by reaction of hypophosphorous acid and potassium carbonate solution, and then evaporating, (2) by reaction of potassium hydroxide solution and phosphorus on heating (poisonous phosphine gas evolved). | [Flammability and Explosibility]
