Fe3(SO4)4, also known as Iron(III) Sulfate, is a chemical compound consisting of 3 iron atoms and 4 sulfate molecules. Its English name is Iron(III) Sulfate. The atomic mass of this compound is 63.546 grams/mol for Iron and 96.06 grams/mol for Sulfate. The molecular mass of Fe3(SO4)4 is 399.877 g/mol. The Fe3(SO4)4 molecule is structured with each Iron atom bonded to 4 Oxygen atoms through covalent bonds to form the Fe3+ ion and 4 SO4– ions.
In terms of physical properties, Fe3(SO4)4 is a solid, reddish-brown substance. This substance has no distinctive odor and has a neutral pH value. The chemical properties of Fe3(SO4)4 are demonstrated through its ability to react with other substances such as metals, acids, non-metals, and salts.
Fe3(SO4)4 can react with metals like Cu, Ag, Au, Pt to form the sulfate salt of that metal and metallic Iron. It can also react with strong acids such as HCl, H2SO4 to form salts and Hydrogen gas. In addition, Fe3(SO4)4 can react with non-metals such as Cl2, Br2 to form salts and Oxygen gas.
Fe3(SO4)4 can be synthesized by passing SO3 gas over metallic Iron at high temperatures or by the reaction between metallic Iron and concentrated, hot H2SO4. On an industrial scale, Fe3(SO4)4 is typically produced by electrolysis of a FeSO4 solution.
