WebAnswer (1 of 4): The oxidation number of Cr is +5. Oxygen usually has an oxidation number of -2. Since there are 5 oxygen atoms, the total oxidation number is -10. The compound Cr2O5 is in a neutral state so the net oxidation number must be 0. In that case, Cr has an oxidation number of +5.

Weband muscle tone. Unlike many other metals, Cr(VI) can combine with oxygen to form water-soluble, negatively charged anions known as yellow chromate (CrO42-) or orange dichromate (Cr2O72-), which adsorb to positively charged sites in contrast to cationic metal species. Therefore, hexavalent chromium WebCalculating the oxidation number of Chromium (Cr) in Cr 2 O 7 2 -: The oxidation state of Oxygen ( O) = -2 The total charge on dichromate ion ( Cr 2 O 7 2 -) = -2 Consider the oxidation state of Chromium ( Cr) = x Now, x × 2 + - 2 × 7 = - 2 2 x - 14 = - 2 x = + 6 Hence, the oxidation number of Chromium in Cr 2 O 7 2 - is + 6.
