1. (a) K₂Cr2O7 reacts with Fe(II) to produce Cr(III) and Fe(III) in acid medium. Write down the balanced equation and construct the cell. Calculate the standard potential and equilibrium constant for this reaction at 298 K? (Given standard reduction potentials, Eº for chromium system is 1.33 V and Eº for iron system is 0.77 V). (b) Also discuss the effect of pH on the change in potential for chromium system in acid medium.
