What is the charge of PPh3 when calculating oxidation states?

When calculating oxidation states of compounds containing PPh3 (triphenylphosphine), each phenyl group (Ph) is considered electrically neutral and contributes zero charge. Therefore, the charge of PPh3 is equal to the charge of the phosphorus atom in the compound. Phosphorus typically has an oxidation state of +3 in PPh3, making the overall charge of PPh3 neutral.
