Most common is the dark violet hygroscopic solid. An anhydrous green form is also known. Chromium(III) nitrate compounds are of a limited commercial importance, finding some applications in the dyeing industry. It is common in academic laboratories for the synthesis of chromium coordination complexes.
http://strategic-metal.com/products/chromium/chromium-nitrate-crno33x9h2o/ WebThe most common oxidation states for Cr are 0, +3 and +6. Chromium is most commonly found in the +3 state, which is fortunate since the +3 state is considered benign as opposed to the +6 that is toxic. At Inorganic Ventures we note the oxidation state of chromium in a given CRM by writing Cr +3 or Cr +6.
