In the phosphate ion, the oxidation number of phosphorous is+5. The sum of the oxidation numbers in PO43-, a polyatomic ion, is -3, the charge of the ion.
We assign -2 as the oxidation number of each O and x as the oxidation number of P and write the following equation:
x + 4(-2) = -3
x = +5.

THE OXIDATION NUMBER OF PHOSPHORUS IN PO4^-3
P+(-2)(4)^-3
P-8=-3
P=-3+8
P=+5
THEREFORE +5 IS THE OXIDATION NUMBER OF PHOSPHORUS IN PO4^-3

SOLUTION:

PO4^-3
P+(-2)(4)^-3
P-8=-3
P=-3+8
P=+5
THEREFORE +5 IS THE OXIDATION NUMBER OF PHOSPHORUS IN PO4^-3
