 Did a lab today by titrating potassium dichromate into and unknown iron solution.

The equation is

14H⁺ + 6Fe²⁺ + Cr₂O₇^2-  2Cr³⁺ + 6Fe³⁺ + 7H₂O

But is says that since the reduction of one dichromate ion to chromium III involves six electrons, the redox concentration of the solution is six times its concentration.

I calculated the concentration the potassium dichromate but now do I multiply it by 6?

Just read stiochiometry of this reaction:
1/6 mole of dichromate is reduced by 1 mole of iron(II)

No idea what a

redox concentration of the solution

is.

Could be they mean normality.
