41. Given the following ions, how many different compounds are possible. List them with the correct name and formula.

Fe3(PO4)2 Iron(II) Phosphate
Fe3(PO3)2 iron(II) Phosphite
Fe(PO4) Iron(III) Phosphate
FePO3 (Iron (iii) phosphite.
Explanation:
The ions given are
Fe^3+
Fe^2+
PO4^3-
PO3^3-
The ionic compounds or electrically neutral compounds that can be formed from the cations and anions given are :
Fe^3+ + PO3^3-= Fe3(PO4)2 the ions are balanced. the compound formed is Iron(II) Phosphate
Fe^2++PO4^3-= Fe3(PO3)2 is iron(II)Phosphite
The compound formed is balanced with the charges provided on the ions.
Fe^3+ + PO4^3-= Fe(PO4) the charge on the anion and cation are equal.
THE COMPOUND FORMED IS Iron(III) Phosphate
Fe^3++ PO3^3= FePO3
Fe^3+ + PO^3-= FePO3 (Iron (iii) phosphite.
