Chromium is one of the toxic substances in the environment. Reduction of Cr (VI) to Cr (III) is environmentally favorable as the latter species is not toxic to most living organisms and also has a low mobility and bioavailability. Ferrous iron is one possible reductant implicated as a major contributor to the removal of Cr (VI) from suboxic and anoxic waters and soils. Cr (VI) appears as Cr₂O₇²¯ and the form of Cr (III) is Cr³⁺. Establish this widespread reaction and balance it. Show each step of balancing.
