Calcium phosphate monobasic Usage And Synthesis

Chemical Properties

white crystalline powder

Physical properties

Colorless shiny crystals, granules or powder; the impure material is hygro scopic due to the presence of trace phosphoric acid and other impurities; acid taste; density (monohydrate 2.22 g/cm³); monohydrate loses water at 100°C; decomposes at 200°C; moderately soluble in water; aqueous solution acidic; soluble in dilute mineral acids and acetic acid.

Uses

Chiefly in fertilizers; as acidulant in baking powders and in wheat flours; mineral supplement for foods and feeds; in enameling.

Preparation

Monobasic calcium phosphate may be prepared in the laboratory by the reaction of calcium carbonate with phosphoric acid:
CaCO₃ + 2H₃PO₄ → Ca(H₂PO₄)2 + CO₂ + H₂O

Definition

ChEBI: Calcium bis(dihydrogenphosphate) is a calcium phosphate. It has a role as a fertilizer.

Flammability and Explosibility

Non flammable
