ferrous ions and Fe3+ is ferric ion
The systematic name for the compound Fe2(SO4)3 is iron(III) sulfate. In this compound, the iron ion has a +3 charge, hence denoted as iron(III), and sulfate is a polyatomic ion with a -2 charge, requiring three sulfate ions to balance the charge of two iron ions.
The compound formula for ferric sulfate is Fe2(SO4)3.
There is no compound like Fe2cl but there is Fecl2 & its common name is 'ferric chloride' .
The compound formula for iron III sulfate is Fe2(SO4)3.
This mean hydrogen oxogen and water is mixed! Not possible, Fe has two possible charges. Fe2+ or Fe3+ Oxygen has one possible charge. O2- If it was (Fe2+)2O2-, then it would have a remaining charge of 2+. To become an ionic compound and electrically neutral. it must be Fe2+O2-, Ferrous Oxide (Old term) or Iron (II) Oxide
Fe2(SO4)3, iron (III) sulfate, is not an element but rather a compound.
The presence of "iron" in a compound indicates that the cation in the compound is likely iron (Fe) in one of its various oxidation states. The specific oxidation state of iron can be determined by the compound's name or formula, such as Fe2+ (ferrous) or Fe3+ (ferric).
The name of Fe2+ according to the Stock system is iron(II).
