2. Use standard reduction table on page 1 to help you answer this question. Cu Metal M Salt bridge 1.0 M M(NO,), 1.0 M Cuso, When the voltaic cell above is hooked up, the voltmeter reads +2.00 V and the mass of the metal electrode M decreases. a. Is electrode “M" the anode or the cathode. Justify your answer. b. Calculate the standard half-cell reduction potential E°red for the electrode “M". c. Identify the solid metal and the metal cation that react at electrode “M". Write the electron configuration for the cation. d. Write the balanced net ionic equation for the overall reaction that takes place in this voltaic cell. e. Describe the direction of electron flow in this cell (quick sketch on your paper or in words). f. If the concentration of metal M were increased, predict what would happen to the cell potential (increase, decrease or stay the same). Justify your answer.
