Cr2O72- + 14H+ + 6I- → 2Cr3+ + 3I2 +7H2O and a solution containing K2CrO7 and H2SO4, draw a cell diagram showing the anode and cathode reactions, the direction of electron flow, the ion migration, and the signs of the electrodes. Calculate the EMF of the cell using values from a table of reduction potentials.
The cell diagram is shown as below:
The cell notation is
I- / I2 // Cr2 O72- / Cr3+
anode // cathode
