What is the oxidation number of Cr2O72? - Answers
2024年5月27日 · The oxidation number of Cr in Cr2O7^2- ion is +6. Each oxygen atom has a -2 charge, and the overall charge of the ion is 2-, so combining the charges gives -2*(-7) = -14.
The oxidising strength of Cr2O72- is greatest in a solution of pH?
2018年5月28日 · Well, typically we deploy dichromate oxidants in AN ACIDIC solution.... And so I suppose that pH=1.0 In an acid milieu dichromate undergoes reduction to chromic ion... underbrace(Cr_2O_7^(2-))_"orange red" +14H^+ + 6e^(-)rarr underbrace(2Cr^(3+))_"green" + 7H_2O(l) Some chromate ion, CrO_4^(2-), MAY be formed in acidic solution...but this is NOT a redox solution...and chromate is still Cr(VI+)...
