Chromium Sulfate

Chromium sulfate is a chemical compound with the formula Cr2(SO4)3. It is a violet-colored solid that is soluble in water and has a high melting point. The compound is commonly used as a mordant in textile dyeing and in tanning leather.

The chromium ion in chromium sulfate has a +3 oxidation state, while the sulfate ion has a -2 charge. The compound can be prepared by reacting chromium hydroxide or chromium oxide with sulfuric acid.

In its solid form, chromium sulfate forms crystals with a triclinic structure. Each chromium ion is surrounded by six sulfate ions, forming an octahedral shape. The compound is hygroscopic, meaning it absorbs moisture from the air.

Chromium sulfate is also used in the production of other chromium compounds, such as chrome alum and chromium oxide. It is also used in the production of catalysts and in the manufacturing of pigments for paints and coatings.
