Consider the following voltaic cell: Voltmeter Salt bridgo Zn Co 1 M Co2+ (a) in which direction do electrons flow in the external circuit? (b) In which half-cell does reduction occur? (C) In which half-cell do electrons leave the cell? (d) At which electrode are electrons generated? (e) Which electrode is positively charged? (f ) Which electrode increases in mass during cell operation? (g) Suggest a solution for the anode electrolyte. (h) Suggest a pair of ions for the salt bridge. () For which electrode could you use an inactive material? ) In which direction do cations within the salt bridge move to maintain charge neutrality? (k) Write balanced half-reactions and the overall cell reaction.
