A voltaic cell is assembled by using two 30mL beackers. In one beaker, Ag metal is used with 10mL of 1 M AgNO3. IN another beaker, Zn metal is used as the electrode with 10mL of 1 M ZnSO4. The beakers are connected with a salt bridge and the measured cell potential, E0 cell is 1.50 V. The Zn electrode is negative.
If the standard silver half-reaction potential is set to 0.00V, calculate the potential for the zinc half reaction.
If the standard silver half-reaction potential is set to .80V, calculate the potential for the zinc half-reaction.
Write the net ionic equation for the reaction that occurs in this voltaic cell.
