... The substance that could carry out a reduction of vanadium must be on the right-hand side of the half-equations, so it cannot be iodine. Sulfur dioxide being oxidised to sulfate(VI) ions has a potential of −0.17 V. Adding this to each of the potentials for the vanadium half-equations gives +0.83 V ( ...
