1. Identify the anode and the cathode in the following combinations of half-cells. Remember that Ecell Eox + Ered and that Egell must be positive in order to function as a voltaic cell. You may use tables of standard reduction potentials in your text. a) Fe/Fe and Zn/Zn anode cathode b) Ag/Ag' and Sn/Sn c) Zn/Zn*2 and Cu/Cu2 d) Sn/Sn2 and Al/Al 2. Sketch a voltaic cell consisting of lead anode and a copper cathode. Clearly label both electrodes, the voltmeter, salt bridge, the direction of electron flow, and suggest possible salts which could be dissolved in the half cells to complete the cell.3. Give the cell notation for a voltaic cell consisting of a metallic iron anode immersed in a solution of FeCly, and a metallic copper cathode immersed in aqueous Cu(NO3)2.

Answer :

a) Fe is the anode and Cu is the cathode. b) Ag is the cathode and Sn is anode c) Zn is anode and Cu is cathode d) Al is cathode and Sn anode.

2. What type of salts are used in the half cells to complete the cell?

Possible salts that can be dissolved in half cell to complete the cell : potassium chloride (KCl) and potassium nitrate (KNO3) are better inert salts.

A salt bridge's main function is to maintain electrical neutrality between two beakers and to do so the salt used must be inert. The ions must to move to and forth between the two half cells.

3. Cell notation for a voltaic cell consisting of metallic iron anode immersed in a solution of FeCl3 and a metallic copper cathode immersed in aqueous Cu(NO3)2.

Fe°|Fe3+|| Cu2+|Cu

Left electrode -- anode and right electrode -- cathode.
