Cadmium and a solution of cadmium(II) nitrate are used with tin and a solution of tin(II) nitrate to construct a galvanic cell.
1)
The reaction run initially at standard state with 100-mL samples of each solution is allowed to proceed until 8.0 g of tin has been deposited on the tin electrode. Calculate the cell potential at this point.
2) A similar cell is constructed , except the concentration of the tin(II) nitrate is unknown, and the concentration of the cadmium nitrate solution is 1.0 M. If the potential of the cell is found to be 0.39V, what is the concentration of tin(II) nitrate in the unknown solution?
3) What ratio of product ions to reactant ions would cause the cell potential to be 10% lower than the standard cell potential?
