+5
Phosphate is PO43- ion. The oxidation numbers are -2 for each O and +5 for P
NaH2PO4(aq) --> Na+(aq) + H2PO4(aq)sodium dihydrogen phosphate --> sodium ion + dihydrogen phosphate ionExplanationDissociation is the breakdown of soluble salts into their respective ions. Sodium dihydrogen phosphate is made up of two ions - sodium and dihydrogen phosphate. Therefore the dissociation of sodium dihydrogen phosphate will produce sodium and dihydrogen phosphate ions.
-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.
H2PO4- is called dihydrogen phosphate ion. It is the conjugate base of Phosphoric Acid H3PO4 and the conjugate acid of monohydrogen phosphate ion HPO42-Liquid
The chemical formula for dihydrogen phosphate ion is H2PO4-
The dihydrogen phosphate ion - (H2PO4)-is an anion.
There are two possibillities:Monohydrogen Phosphate ion: HPO42-Dihydrogen Phosphate ion: H2PO4-

The answer is 81 protons.
Dihydrogen phosphate ion

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.
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
