What is the correct formula for mercury(II) phosphate?

Explanation:
The correct formula for mercury(II) phosphate is represented as Hg3(PO4)2. This is derived from understanding the charge of mercury and the phosphate ion. Mercury(II) indicates that mercury has a +2 oxidation state. The phosphate ion (PO4) has a -3 charge. To balance the charges, we need three mercury ions to provide a total charge of +6 (3 × +2) and two phosphate ions, which contribute a total charge of -6 (2 × -3). This results in a neutral compound, satisfying the requirement for a stable ionic compound. Thus, the formula Hg3(PO4)2 accurately represents the composition of mercury(II) phosphate, with three mercury atoms and two phosphate groups.
