Question

The plating solution you will be using is Watts Nickel Pure, a nickel sulfamate solution. Nickel sulfamate is Ni(NH SO;)h in H2O. Use this diagram of an electrolytic cell to answer the following questions. You may want to refer back to Experiment 15 on Redox Equilibria and Electrochemistry Power supply Voltmeter Metal cathode Metal anode metal-solution interface metal-solution interíace Solution H20 LLC Qi. On the cell diagram, mark the following a. Direction of electron flow b. Direction of flow for the positive metal ion in solution c. Charge on the positive metal ior d. At which clectrode the nickel will be deposited e. Which electrode will be the nickel wire Why does the concentration of nickel ions in solution stay the same during the Q2. electrolysis?

Explanation / Answer

a) The electrons flow from anode to cathode.

b) The positive metal ion moves towards cathode.

c) The positive metal ion is having dipositive charge.

d) The Ni+2 ion from impure metal will be deposited at cathode of pure form of Ni.

e) Cathode is a nickel wire
