Cr2(So4)2

The chemical compound Cr2(SO4)2 is commonly known as chromium(II) sulfate. It consists of two chromium (Cr) ions and two sulfate (SO4) ions, with a chemical formula of Cr2(SO4)2.

The compound can be formed by reacting chromium(II) hydroxide or chromium(II) oxide with sulfuric acid. It is a blue-green solid that is insoluble in water but soluble in acids.

The chromium ions in the compound have a +2 oxidation state. Each chromium ion is coordinated to six oxygen atoms from four sulfate groups, forming an octahedral geometry. The sulfate ions act as bidentate ligands, meaning that each sulfate ion binds to the chromium ion through two oxygen atoms.

This compound has some important applications in industry, including as a mordant in textile dyeing and as a catalyst for organic reactions. However, it is important to handle it with caution as it can be toxic if ingested or inhaled.
