How to find the Oxidation Number for Cr in the Cr2O7 2- ion. (Dichromate ion)
To find the oxidation number for Cr in Cr2O7 2- (the Dichromate ion), and each element in the ion, we use few simple rules and some simple math. First, since the Dichromate ion has an overall charge of 2- we could say that the oxidation numbers in Cr2O7 2- need to add up to charge on the ion. We write the oxidation number (O.N.) for elements ...
