Problem

A common shorthand way to represent a voltaic cell is

anode | anode  solution || cathode  solution | cathode

A double vertical line represents a salt bridge or a porous barrier. A single vertical line represents a change in phase, such as from solid to solution.

For the following reaction:

ClO3-(aq) + 3 Cu(s) + 6 H+(aq) →  Cl-(aq) + 3 Cu2+(aq) + 3 H2O(l)

Pt is used as an inert electrode in contact with the ClO3- and Cl-. Calculate the standard emf using data in Appendix E and given the following:

ClO3-(aq) + 6 H+(aq) + 6 e-  →  Cl-(aq) + 3 H2O(l);       Eo= 1.45 V
