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.
