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. (a) Write the half-reactions and overall cell reaction represented by Fe|Fe2+| |Ag+|Ag; sketch the cell. (b) Write the half-reactions and overall cell reaction represented by Zn|Zn2+| |H+|H2; sketch the cell. (c) Using the notation just described, represent a cell based on 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-. Sketch the cell.
