What is the oxidation state of chromium in K2Cr2O7? Mon Nov 17 2008 · Oxidation number of K = + 1 oxidation number of O = -2 Let the oxidation number of Cr =X So +1(2) + X(2) + -2(7) = 0 2 + X(2) - 14 = 0 -12 + X(2) = … Oxidation state of O:- -2; Let the oxidation state of Cr be :- x ; And we know that net charge on a compound is 0. Therefore the equation will be :-(1×2)+(2×x)+[7×(-2)]=0. 2+2x-14=0. 2x-12=0. 2x=12. Therefore x=12/2=6. So in K2Cr2O7 the oxidation number of Cr is +6.
