Sodium hypophosphite. It is soluble in water, and easily absorbs moisture from the air. 2. If the acid is stronger than the base then the salt is an acidic salt and if the base is stronger than the acid then it is a basic salt. ChemiDay you always could choose go nuts or keep calm with us or without. Sodium Hypophosphite (CAS NO.7681-53-0) is used for pharmaceutical and electroless nickel plating, it is used as a strong reductant.In the method of electroless nickel plating, a durable nickel-phosphorus film can coat objects with irregular surfaces, and can widely be used ionics, aviation and the petroleum field.It also can be used as a food additive. Hypophosphorous acid and its sodium salt (sodium hypophosphite) are used as powerful r educing agents in various field. 2 indicate that the complex salt of NaCa(H 2 PO 2) 3 is an incompatible double-salt which decomposes into the Ca(H 2 PO 2) 2 solid salt and a NaH 2 PO 2-containing solution upon water addition.The co-saturated point F has a trace solubility of Ca(H 2 PO 2) 2 which makes it very close to point G (NaH 2 PO 2 saturated in water). Out the four,NaH 2 PO 3,NaH 2 PO 4 and Na 2 HPO 4 are acidic salts. I expected this to be a very strong reductor, but it is acting very slowly, much slower than I expected. There are several international sellers who offer it, mostly from China. The IUPAC for this compound is sodium di hydrogen phosphate.
