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
