Answer:
half cell is one of the two electrodes in a galvanic cell or simple battery. For example, in the Zn−Cu
battery, the two half cells make an oxidizing-reducing couple. Placing a piece of reactant in an electrolyte solution makes a half cell. Unless it is connected to another half cell via an electric conductor and salt bridge, no reaction will take place in a half cell.
On the cathode, reduction takes place.
Oxidant+ne−→Reductant
Example: Cu2++2e−→Cu
Cu2+
is the oxidizing agent and Cu
the reducing agent.
On the anode, oxidation takes place.
Reductant→Oxidant+ne−
Example: Zn→Zn2++2e−
.
Zn
is the reducing agent, and Zn2+ the oxidizing agent.
