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.
