Question

Draw a labelled diagram of the apparatus that includes the anode, the cathode, the electrolyte, the direction of ion flow and the direction of electron flow provided by the power source. 28. Answer (4 Marks) Cu 29. Write and identify the half-reactions and net reaction. Answer (3 Marks) Cathode Half-Reaction Anode Half-Reaction Net Reaction 30. Calculate the theoretical potential difference of this cell. Answer (2 Mark) Chemistry so Unit C Module 6 S Besides deposition of Cu(s), what other empirical observation is expected. Identify the electrode where this empirical evidence would be observed. 31. Answer (2 Marks Lesson 3 Use the following information to answer the next question. Electroplating is a widely used process. Rhodium is sometimes plated onto less precious metal and sold as white gold. The plating of rhodium is simplified in the following half reaction. Plating of Rhodium Rh3(aq)+3eRh(s) 32. The power supply used in commercial electroplating provides a vat with approximately 1.50 x 103 A of current for 20.0 minutes. Calculate the mass of rhodium plated. Answer (4 Marks) Page 20 of 20
