The charge of a phosphate ion (PO4) in K3PO4 is -3. Here's why:

1. K3PO4 is a compound made up of potassium ions (K+) and phosphate ions (PO4).

2. The subscript '3' in K3PO4 indicates that there are three potassium ions, each with a charge of +1, contributing a total charge of +3.

3. For the compound to be neutral overall, the charge of the phosphate ion must balance out the +3 charge from the potassium ions.

4. Therefore, the charge of the phosphate ion is -3.
