Chromium 6 compounds
WebChromium exists in a wide range of oxidation states. Most common are the oxidation states: +2, +3, and +6. Chromium (II) is not stable and is a strong reducing agent. It should be noted, the most stable oxidation state for chromium compounds is +3. Moreover, it can also exist in the oxidation states +1, +4, and +5. However, these are much rarer. WebJul 20, 2024 · The most strongly oxidizing oxyanions often contain an element in its highest possible oxidation state, that is, with an oxidation number equal to the periodic group number. For example, NO 3– contains nitrogen in a +5 oxidation state, Cr 2 O 72– (seen below) contains chromium +6, and has manganese +7.
