Question- Iron(II) in aqueous solution can be quantities by anoxidation- reduction process using dichromate,Cr2O72-
Cr2O72-(aq) + 6Fe2+(aq) +14 H+(aq) ? 2Cr3+ (aq) + 6Fe3+(aq) +7H2O
Write the balanced half reactions for the oxidation of Iron (II)and the reduction of dichromate,
Please define why you think that's the right answer
