Solubility in Acidic Liquids
pH Performance of Suspension
There are two crystal types of dibasic calcium phosphate, namely anhydrous and dihydrate crystals. It is a white powder without odor or taste and keeps chemically stable at regular room environments. Though its solubility in water is extremely poor, the compound dissolves rapidly in diluted HCl and HNO3, and shows no solubility in alcohol solvents.
