Calcium Hypophosphate Usage And Synthesis
DescriptionCalcium hypophosphate has the molecular formula of Ca2P2O4. It can be formed by an aqueous solution of hypophosphorus acid and a soluble calcium salt:
2CaCl2 (aq) +H4P2O4 (aq) ? Ca2P2O4 (solid) + 2HCl (aq)
The calcium salt solution is added until no precipitate results. Alternatively, sodium hypophosphate can be used to produce a basic solution instead of acidic. The basic product is a hexahydrate, Ca2P2O4·6H2O. The acidic product is a dihydrate, CaH2P2O4·2H2O. The former salt is insoluble in water but slightly soluble in acetic acid. It redissolves in excess hypophosphoric acid. Its CAS number is 75499-50-2. The acidic salt is more soluble in water at 16.8 g/100 ml at 20°C. If this salt is heated, it loses the two waters of hydration at about 125–130°C. The crystal structure of the anhydrate or the hydrate has not been determined.
Calcium hypophosphate has been used as a rootdesensitizing agent in Dentistry. It has been prescribed as a source of calcium and phosphorus in the human body by Homopathic practioners until it was discovered that this compound crystallizes in tissues and may add to kidney stones and gall stones.
