Q. What is the color of chromium sulfate?

Answer

Crystalline chromic sulfate ranges in color from a deep green to violet. Fabric dyes, pottery, paints/inks, and textiles. Inorganic compounds with the formula CrSO4n H2O are known as chromium(II) sulfates. There are a number of related hydrated salts in existence. The pentahydrate can be recognized by its distinctive blue color and its easy dissolution in water. Not flammable, obviously. If released, this material poses a significant risk to the environment. The environmental impact of this must be mitigated as soon as possible. It is possible to find crystalline salts of chromous sulfate in the pentahydrate, trihydrate, monohydrate, and anhydrous forms, with structures that are comparable to those of their copper(II) sulfate counterparts. All of these compounds share a coordination geometry in which the Cr(II) core is octahedral, with six oxygen centers coupled to Cr(II) by a combination of water and sulfate ligands.
