a "fake" chemical reaction
A reaction that shows the electrons involved in an oxidation or reduction step of a reaction.
Either the oxidation part or the reduction part of a redox reaction.
Refers to the chemical processes occurring at each electrode. The potential of the two half-reactions add to give us the overall cell potential.
A half reaction is either the oxidation or reduction reaction component of a redox reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction.
