Phosphorus is in +5 O.S.
Oxygen is in -2 O.S.
Phosphate is PO43- ion. The oxidation numbers are -2 for each O and +5 for P
+5
-3. The sum of oxidation numbers of the atoms in all polyatomic ion is the net charge - its part of the definition of oxidation number.
This will depend on the valance of the aluminum ion. The phosphate ion has a -3 oxidation number (PO43-). Some compounds which could be formed: With Al (II) ion - Al3(PO4)2 With Al (III) ion - AlPO4

AlPO4. This is because an aluminum ion has an oxidation number of 3+ and the phosphate ion has an oxidation number of 3- and thus combine in a 1:1 ratio.

The phosphate ion PO43-
a phosphate ion is PO43-
There are two possibillities:Monohydrogen Phosphate ion: HPO42-Dihydrogen Phosphate ion: H2PO4-
An anion. For which element, I am not sure. Let someone else answer that.
The phosphate ion is (PO4)3-.
The formula for hydrogen phosphate ion is: H2PO4−
The phosphate ion is PO43-
