Electrode Potential and Electrochemical Cells Question 1 The diagram below shows the experimental setup for a typical electrochemical cell that contains two standard half-cells. The cell operates according to the reaction represented by the following equation. Zn(s) + Ni2+ (aq) Ni(s) + Zn2+ (aq) Salt Bridge SO, X SO (a) Identify M and M2. in the diagram. (2 marks) (b) Indicate which of the metal electrodes is the cathode. Write the balanced equation for the reaction that occurs in the half-cell containing the cathode. (2 marks) (c) Describe what would happen to the cell voltage if the salt bridge was removed. Explain the reasons for this. (2 marks)
