Calculate the potential (emf) of a working galvanic cell that is based on these two half cells and standard potentials (both written as reduction reactions) in an aqueous solution. Cr3+(aq) → Cr2+(aq) E°(Cr3+/Cr2+) = â’0.50 V IO2â’(aq) → I2(aq) E°( IO2â’/I2) = +1.80 V The pH of this cell is 14, and the concentrations of species are: Cr3+ is 0.5 M, Cr2+ is 0.2 M, IO2â’ is 0.5 M and I2 is 0.8 M.
