2+ Determine the cell potential (E) from the following half-cells: Pbº/Pb²+ and Znº/Zn² where [Pb²+] = .86M and [Zn²+] = 0.35 M. Calculate K for this reaction. How long in hours would you have to let it go until you lower the voltage to 85 percent of the E from the Nernst equation at 7.2 amps?

Q: Based on the sign of the standard cell potential, ?∘cell,Ecell°, classify these reactions as…

A:

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
