What would be the effect on measured cell potential if some solution in one well spilled over and mixed with that in the other well? For example, suppose some Cu solution spilled into the compartment with the zinc elecrode and Zn solution. (Consider possible interactions that might now happen.)

Solution:

When some of the Cu2+ spilled into the compartment with Zn electrode and Zn2+ ions, then the metalic Cu is deposited on Zn electrode and hence, cell potential will be reduced.

Zn +Cu2+ = Zn2+ + Cu (metal)

This Cu metal deposited on Zn electrode and hence minimizes the cell potential.

Do measured cell potentials show any effect of solution concentration on cell potential for the reactions performed in this experiment? For example, would the potential have changed for 0.1 M solutions from standard conditions of 1 M solutions. Yes, the Nernst equation shows potential is dependent on solution concentrations. No, the Nernst equation does not show potential is dependent on solution concentrations. The potential would change if the cathode and anode were mislabeled. Potential is dependent on concentration, but in...

A concentration cell is called such because both the anode and cathode are build from the same components, meaning the standard cell potential is zero volts and the measured cell potential entirely depends on the relative concentration of ions on either side of the electrochemical cell. Consider the following concentration cell Zns)lZn2() (77M)Zn2()(0.50 M)| Znø) 0.50 M) Zn Given that the concentration of zinc ions in the cathode are 0.50 M, what would the concentration of zinc ions need to...

In a copper-zinc voltaic cell, one half-cell consists of a ZnZn electrode inserted in a solution of zinc sulfate and the other half-cell consists of a CuCu electrode inserted in a copper sulfate solution. These two half-cells are separated by a salt bridge. At the zinc electrode (anode), ZnZn metal undergoes oxidation by losing two electrons and enters the solution as Zn2+Zn2+ ions. The oxidation half-cell reaction that takes place at the anode is Zn(s)→Zn2+(aq)+2e−Zn(s)→Zn2+(aq)+2e− The CuCu ions undergo reduction...
