Phosphates are important in [[biochemistry]]. Phosphates have the formula PO<sub>4</sub><sup>3-</sup> and a molar mass of 94.973 g/mol. An example of a phosphate is [[sodium phosphate]]. Three different types of phosphates are known. They are orthophosphate, PO<sub>4</sub><sup>3-</sup>; metaphosphate, PO<sub>3</sub><sup>2-</sup>; and py
