Zirconium(IV) phosphate is an inorganic crystalline material widely researched for ion-exchange and nuclear waste management. Given that zirconium exists as the cation Zr4+\text{Zr}^{4+}Zr4+ and the phosphate group is the polyatomic anion PO43−\text{PO}_4^{3-}PO43−, what is the correct empirical chemical formula for neutral zirconium(IV) phosphate?
Zr4(PO4)3\text{Zr}_4(\text{PO}_4)_3Zr4(PO4)3
Zr3(PO4)4\text{Zr}_3(\text{PO}_4)_4Zr3(PO4)4
Zr(PO4)4\text{Zr}(\text{PO}_4)_4Zr(PO4)4
Zr4PO4\text{Zr}_4\text{PO}_4Zr4PO4
