Concept explainers

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.

Question

If the Sn**(aq) + 2e → Sn2*(aq) was used as a reference for the electrode potential table
instead of the standard hydrogen half cell, what would the potential of the following half cell
be?
Cu2*(aq) + 2e → Cu(s)
-0.49 V
+0.19 V
+0.49 V
O -0.19 V
