The structural formula of AsO4^3- ion is a resonance hybrid of several canonical structures, equivalent to each other. In any of them, a central arsenic atom, which has 5 valence electrons, makes a double bond with an electrically neutral oxygen atom, and three identical single bonds with as many oxygen atoms bearing a single negative charge. Since oxygen is more electronegative than arsenic, the latter nominally loses in favor of the oxygen atoms all of the five electrons it employed in making those four bonds, so that it can be assigned a +5 oxidation number.
In equivalent structures, the As=O double bond is replaced by an As—->O coordinate bond. The results do not change: the whole lone pair employed by As in making that bond is nominally lost in favor of the oxygen atom, so that the oxidation number of As remains +5.

Oxygen usually has an oxidation number of 2-. Because there are 4 oxygens, they add a 4(-2) = 8- charge to phosphate. We know the charge of phosphate plus the charge of the oxygens must be -3, so the phosphorus in phosphate has oxidation state +5. Hope this helps!

The chemical formula of arsenate ion is "AsO₄³⁻" instead.
In AsO₄³⁻, the oxidation state of O is -2 as usual, and the total oxidation state is equal to the charge carries by the ion, i.e. -3.
In AsO₃³⁻: (Oxidation state of As) + 4(-2) = -3 Oxidation state of As = +5
(The above method is used to calculate oxidation number.) (Although oxidation state and oxidation number are different in concept, their values are the same.)

AsO4 -³ is an ion.
So to calculate the oxidation state we have to equate the individual charges sum to the toral charge on rhe ion.
Let the oxidation of As be [math]x[/math].
And we know the oxidation of Oxyegen ion = -2
[math]x + 4(-2) = -3[/math]
[math]x -8 = -3[/math]
[math]x = 5[/math]
Therefore, Arsenic have 5 oxidation number.

Arsenate ion is AsO4^3-
Oxidation number of As in ASO4^3- is +5
Calculation:
x + 4 ( O) = -3
x + 4 ( -2) = -3
x - 8 = -3
x = +5
Hope this will be helpful.
