Faraday's Law 8. a) the mass of Zn deposited at the cathode in 42.5 minutes when 1.87 A of current is passed through an aqueous solution of Zn2+ b) the time required to produce 2.79 g 12 at the anode if a current of 1.75 A is passed through KI (aq) c) The mass of a 1999 Canadian penny is 2.25 g and is 1.6% by mass plated copper. To plate the copper onto the penny, 2.0 A is passed through a 2.0 M solution of CuSO4. How long would it take (in seconds) to deposit this amount of copper onto a single penny? Nernst Equation 9. A voltaic cell represented by the following cell diagram has Ecell = 1.250 V. What must be [Ag+] in the cell? Zn (s) | Zn2+ (1.00 M) || Ag* (x M) | Ag (s) 10. Use the Nernst equation and reduction potential data from (Petrucci's Appendix D; OpenStax's Table 16.1) to calculate Ecell for the following cell: Al (s) | Al3+ (0.18 M) || Fe2+ (0.85 M) | Fe (s) Faraday's Law 8. a) the mass of Zn deposited at the cathode in 42.5 minutes when 1.87 A of current is passed through an aqueous solution of Zn2+ b) the time required to produce 2.79 g 12 at the anode if a current of 1.75 A is passed through KI (aq) c) The mass of a 1999 Canadian penny is 2.25 g and is 1.6% by mass plated copper.
