Question

What is ionic compound of Fe3+ SO4 2-?

Answer 1

The ionic compound of Fe3+ and SO4 2- would be Fe2(SO4)3 or Iron (III) sulfate. It is a rhombic crystalline salt and soluble in water at room temperature. It is used in dyeing as a mordant, and as a coagulant for industrial wastes.

Answer 2

The answer:

The ionic compound is Fe2(SO4)3

or It  also called Iron (III) sulfate.

The explanation:

the ionic compound is consist of cations with a positive charge and anions with a negative charge. It is neutral. The chemical compound consist of ions matches and held together by ionic bonding.  

when Fe 3+ (cation) and (SO4) 2- (anion)

by exchange so, the ionic compound is

Fe2(SO4)3 , It is  soluble in water at room temperature
