The left half cell consists of a Sn electrode immersed in a solution of SnCl 2 .

Question

The left half cell consists of a Sn electrode immersed in a solution of SnCl2. The right half cell consists of a MnO2 electrode immersed in a solution of MnCl2.

a. Use standard electrode potential

Table standard potentilas of chemical to write the balanced chemical equation for the above cell reaction when it is producing a positive cell potential.

b. Calculate the cell voltage under standard conditions.

c. Use the Nernst Eq. Ecell = Eocell - (0.0592/n) log10(Q) to calculate the cell potential when

[Mn2+] = 0.010 M, [Sn2+] = 0.010 M, and [H+] = 1.00 M.
