c) Electrolysis of nickel (II) nitrate is also known as an electroplating process. During the electroplating process, carbon electrode was used for anode and cathode. From the observation, oxygen is produced at the anode whereas hydrogen and nickel are produced at the cathode. i) Sketch the electroplating process with complete labelling (4 marks) ii) Calculate the mass of nickel obtained from nickel (II) nitrate solution when a current of 1.5A is used for 30 minutes. Given the 1 mole of electrons, e=96500C
