Question 1
Consider the reaction Fe + Sn
2+(1 × 10
–3 M) → Fe
2+(1.0 M) + Sn. Calculate the voltage theoretically generated by the cell.
Question 2
Gold can be electrochemically "plated" onto a less expensive metal by submerging the object in a solution of gold(III) and applying an electric current to drive the following half-reaction:
Au
3+ + 3e
–→ Au(s)
How many grams of gold will be formed if a current of 2.37 A is applied for 71 minutes?
