The formula for Tin (IV) Phosphate is Sn(PO₄)₂.
In this compound, Tin (IV) refers to the Tin ion with a +4 charge, which is represented by the symbol Sn4+. The Phosphate ion, which is a polyatomic ion, has the formula PO₄3- and carries a -3 charge.
To balance the charges in the compound, we need two phosphate ions to balance one tin ion: +4 from one tin ion and -6 from two phosphate ions, resulting in a neutral compound overall. Thus, the formula accurately reflects the correct stoichiometry for the combination of these ions.
