The most common oxidation states of chromium are +6, +3, and +2. A few stable compounds of th…In the +6 oxidation state, the most important species formed by chromium are the chromate, CrO42−, and dichromate, Cr2O72−, ions. These ions form the basis for a series of industrially important salts. Among them are sodium chromate, Na2CrO4, and sodium dichromate, Na2Cr2O7… Chromium forms several commercially valuable oxygen compounds, the most important of which i…Another significant oxygen compound is chromium oxide, also known as chromium sesquioxide or chromic oxide, Cr2O3, in which chromium is in the +3 oxidation state. It is prepared by calcining sodium dichromate in the presence of carbon or sulfur. Chromium oxide is a green powder and is …
