Phosphorus is in +5 O.S.
Oxygen is in -2 O.S.
The oxidation number for the dihydrogen phosphate ion (H2PO4-) is +1 for each hydrogen atom, -2 for the oxygen atom, and +5 for the phosphorus atom.
To find the oxidation number of phosphorus in phosphate (PO4), consider that oxygen typically has an oxidation number of -2. Since there are four oxygen atoms in phosphate, their total charge is -8. The overall charge of the phosphate ion is -3, so the oxidation number of phosphorus can be calculated as +5 to balance the charges.
The sum of the oxidation numbers in the phosphate ion (PO4^3-) is -3. Each oxygen atom has an oxidation number of -2, totaling -8. The oxidation number for phosphorus is +5 to offset the oxygen atoms and give a total charge of -3 for the ion.
The oxidation number of phosphorus in a hydrogen phosphate ion (HPO4^2-) is +5. This is because oxygen typically has an oxidation number of -2, and there are four oxygen atoms surrounding the phosphorus atom, giving it an oxidation number of +5 to balance the negative charge of the oxygens.
The oxidation state of phosphorus in the phosphate ion (PO43-) is +5. This is because each oxygen atom has an oxidation state of -2, and the overall charge of the ion is -3, so the phosphorus must have an oxidation state of +5 to balance the charges.

The formula of the compound formed between aluminum ions and phosphate ions is AlPO₄, which is known as aluminum phosphate. It is composed of one aluminum ion (Al³⁺) and one phosphate ion (PO₄³⁻) to balance the charges and form a neutral compound.
The oxidation state of phosphorus in the phosphate ion (PO43-) is +5. This is because each oxygen atom has an oxidation state of -2, and the overall charge of the ion is -3, so the phosphorus must have an oxidation state of +5 to balance the charges.
The oxidation number of phosphorus in the phosphate ion (PO43-) is +5. This is determined by the overall charge of the ion and the known oxidation states of oxygen (-2) in compounds. In this case, there are four oxygen atoms each with a -2 charge, resulting in a total charge of -8. The phosphorus atom must have a +5 charge to balance the overall -3 charge of the ion.
P = +5 PO4^3- = -3 4(-2) + p = -3 P =5
It is 5.
In disodium phosphate (Na2HPO4), each sodium (Na) atom has an oxidation number of +1 since it is in Group 1 of the periodic table. The hydrogen atom (H) has an oxidation number of +1, and the phosphate ion (PO4) as a whole has a charge of -3, making the phosphorus atom (P) have an oxidation number of +5.
The charge of a phosphorus (P) ion can vary depending on its oxidation state. For example, in the common phosphate ion (PO4)3-, phosphorus has a charge of +5.
The cobalt in the formula given has an oxidation number of +3, so that the total charge of the two cobalt ions will balance the total charge of the 3 oxide ions, which have an oxidation number of -2 each.
