Avoltaic cell consists of a strip of cadmium metal in a solution of cd(no3)2 in one beaker, and in the other beaker a platinum electrode is immersed in a nacl solution, with cl2 gas bubbled around the electrode. a salt bridge connects the two beakers. part a which electrode serves as the anode, and which as the cathode? which electrode serves as the anode, and which as the cathode? cd serves as the cathode, pt as the anode. pt serves as the cathode, cd as the anode. request answer part b does the cd electrode gain or lose mass as the cell reaction proceeds? does the electrode gain or lose mass as the cell reaction proceeds? the cd electrode will gain mass as the cell reaction proceeds. the cd electrode will lose mass as the cell reaction proceeds. request answer part c write the equation for the overall cell reaction.
