We’re gift asked to determine theoxidation state that phosphorusinPO43– (phosphate ion).

You are watching: What is the oxidation number of phosphorus in the phosphate ion?

Therules for oxidation statesare as follows:

A. General Rules:

1. For an atom in its elemental form (Zn, Cl2, C(graphite), etc.) O.S. = 0

2. For an ion (Li+, Al3+, etc.) O.S. = charge

B. Certain Rules:

1. Group 1A O.S. = +1

2. Team 2A O.S. = +2

3. Hydrogen O.S. = +1, with nonmetals

O.S. = –1 v metals and boron

4. Fluorine O.S. = –1

5. Oxygen O.S. = –1 in peroxides (X2O2, X = team 1A)

O.S. = –1/2 in superoxides (XO2, X = group 1A)

O.S. = –2 in other compounds

6. Group 7A O.S. = –1 (except as soon as bonded to O)

Since PO43– is neither a peroxide or superoxide,the oxidation state of each oxygen atom is –2.
