What is Calcium phosphate monobasic?
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.
The Uses of Calcium phosphate monobasic
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.
