Answer all questions please
Chemistry R122 Study Assignment 10 Electrolysis and Electroplating 1. Molten magnesium bromide is electrolyzed. Draw the electrolytic cell involving this reaction. Indicate in your diagram: a) the sign of the anode and of the cathode. b) which ions migrate to the cathode c) which ions migrate to the anode. d) What is the half reaction that occurs at the anode? e) What is the half reaction that occurs at the cathode? What minimum voltage must be applied to have the overall reaction occur? 2. If a solution of CuClz is electrolyzed, what reaction will occur at the anode when the mÃnimum potential is applied? 3. A proposed battery involves the reaction of Zn(s) and Cl2(8) to give ZnCl2. If you want such a battery to operate for 10 hours and deliver 1.5A current, what is the minimum mass of zinc that the anode must have? 4. A commercial cell for producing F; operates at a current of 1500A from the electrolysis of HF dissolved in KF. 2HF (KF) â H2(g) + F2(g) How long would this cell have to run in order to produce 25 kg of F2? 5. A solution containing P is electrolyzed with a current of 4.00 A. how long will it take to plate out all of the platinum in 0.50L of a 0.010M solution of Pt*?
