11. In order for the cell shown above to produce a voltage of 1.96 V which of the
changes shown below must be made?
O A platinum electrode must be placed in the half-cell on the right.
O The chemical substance in the salt bridge must be KNO3(aq).
O A porous cup must be used.
O The half-cell on the rleft must be acidified.
12. The balanced chemical equation for the operating cell shown above is
O MnO4 (aq) + 8 H*(aq) + 5 Fe?*(aq) – 5 Fe (aq) + Mn²*(aq) +4 H2O()
O MnO2(aq) + 4 H*(aq) + 5 Fe(s) – 5 Fe²*(aq) + Mn²*(aq) + 2 H2O(1I)
5 Fe2-(aq) + Mn²+(aq) + 4 H2O(1) – 2 MnO, (aq) + 16 H*(aq) + 5 Fe(s)
