the process that occurs in one half-cell of a voltaic cell; an equation showing either the reduction or the oxidation of a species in an redox reaction.

The reaction that takes place in a half-cell.

one of two parts of a redox reaction, one of which involves a loss of electrons and the other of which involves a gain of electrons

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.
