Write the ions present in a solution of na3po4.

The ions present in the solution of Na₃PO₄ are:

3Na⁺¹ and 1PO₄⁻³

there are 3 sodium ions (Na⁺¹) are present, these are cations (+).

And 1 phosphate ion (PO₄⁻³) is present, this is anion (-),

When these cations and ions meet together a compound is formed, in this case 3 sodium ions make a bond with 3 oxygens of phosphate and makes a compound of sodium phosphate.
