Iron sulfates contain iron, sulfur and oxygen.
Iron sulfate, also known as ferrous sulfate, contains iron and sulfur. It is a chemical compound composed of one iron atom, one sulfur atom, and four oxygen atoms as sulfate ions.
Iron, Fe, and sulfur, S, are two completely different elements (eg. one is a metal, the other is a yellow powderish non-metal, both insoluble in water)andiron sulfate is a compound, FeSO4, made of three different elements (Fe, S and 4 Oxygen atoms) bound together in a molecule (eg. it is a greenish, soluble salt).
iron (Fe), sulphur (S), oxygen (O)
Two elements, iron and sulpur, make up a molecule of the compound iron sulphide.
Magnesium and Sulfur
3 elements, Iron, Sulfur, and Oxygen aka Ferrous Sulfate
No, iron (II) sulfate is not a gas. It is a solid compound that is commonly found in the form of a white or pale green powder.
If iron(II), then iron sulfate is FeSO4. This has a single Fe atom per molecule (or two Fe in two molecules). If you have iron(III), then iron sulfate is Fe2(SO4)3. This compound has two iron atoms per molecule (or four Fe in two molecules).
Iron (II) sulfate is the correct name for this compound. The Fe ion has a charge of 2 and so does the sulfate ion, so there is no subscript after them.
The product of iron sulfate reacting with calcium carbonate is iron carbonate and calcium sulfate. The iron from the iron sulfate displaces the calcium in the calcium carbonate to form iron carbonate, while the sulfate from the iron sulfate combines with the calcium to form calcium sulfate.
Iron sulfate can be prepared by dissolving iron oxide or iron metal in sulfuric acid. The reaction produces iron sulfate and water. The solution can then be evaporated to obtain solid iron sulfate.
This is the chemical formula of iron(II) sulfate.
