Which statement describes the bonds in iron sulfate (FeSO4)

A. Fe and S are ionically bonded, and S and O also are ionically bonded
B. Fe and S are covalently bonded while S and O also have a covalent bond are covalently bonded
C. Fe and S are covalently bonded, and S and O also have a covalent bond are covalently bonded
D. Fe and S are ionically bonded, while S and O are covalently bonded

1 answer

The correct statement that describes the bonds in iron sulfate (FeSO₄) is:

D. Fe and S are ionically bonded, while S and O are covalently bonded.

In iron sulfate, the iron (Fe) forms a cation (Fe²⁺), which is ionically bonded to the sulfate ion (SO₄²⁻). Within the sulfate ion, sulfur (S) and oxygen (O) are covalently bonded to each other.
