Physical and Chemical Properties
Sodium hypophosphite is a colorless monoclinic crystal or pearl like crystal or white crystalline powder, easily deliquescent, odorless, and salty in taste. Easy to dissolve in water, ethanol, and glycerol, slightly soluble in ammonia and ammonia water, insoluble in ether. The aqueous solution is alkaline. Stable in a dry state, it rapidly decomposes and releases highly toxic and self igniting phosphine gas when heated above 200 ° C. As a strong reducing agent, it can reduce metals such as gold, silver, mercury, nickel, chromium, cobalt, etc. from salts to metallic states. When exposed to strong heat or mixed with oxidants such as potassium chlorate, it will explode. Under normal pressure, heating and evaporating sodium hypophosphite solution can also cause explosions, so evaporation should be carried out under reduced pressure.
In the United States, sodium hypophosphite, hypophosphite, and several other hypophosphates are classified as Class I precursor chemicals and are subject to regulation.
Application:
a.Sodium hypophosphite is used as a reducing agent in electroplating solutions for electroless nickel plating.
b.In the chemical and pharmaceutical industries as a reducing agent.
c.In the food industry as a preservative and antioxidant.
