Question
A patent attorney has asked for your advice concerning the merits of a patent application that describes a single aqueous galvanic cell capable of producing a 12-V potential. Comment.
Step 1
A galvanic cell is a type of electrochemical cell that converts chemical energy into electrical energy through spontaneous redox reactions. In a typical galvanic cell, two electrodes (an anode and a cathode) are immersed in an electrolyte solution, and the Show more…

A patent attorney has asked for your advice concerning the merits of a patent application claiming the invention of an aqueous single galvanic cell capable of producing a 12-V potential. Comment.
In Appendix $D,$ standard electrode potentials range from about $+3 \mathrm{V}$ to $-3 \mathrm{V}$ . Thus, it might seem possible to use a half- cell from each end of this range to construct a cell with a voltage of approximately 6 $\mathrm{V}$ . However, most commercial aqueous voltaic cells have $E^{\circ}$ values of $1.5-2 \mathrm{V} .$ Why are there no aqueous cells with significantly higher potentials?
You want to set up a series of voltaic cells with specific cell potentials. The $\mathrm{Ag}^{+}(\text {aq, } 1.0 \mathrm{M}) | \mathrm{Ag}(\mathrm{s})$ half-cell is one of the compartments. Identify several half-cells that you could use so that the cell potential will be close to (a) $1.7 \mathrm{V}$ and (b) 0.50 V. Consider cells in which the silver cell can be either the cathode or the anode.
