• anode where oxidation occurs.

• cathode where reduction occurs.

• cathode where oxidation occurs.

• Na deposited at cathode.

The following factors affect cell potential EXCEPT

• temperature

• concentration

• gas constant

• electrode potential

What happened in salt bridge?

• anion move to oxidation half cell
