Electrochemical cells in which electrons flow due to oxidation-reduction reaction .
Electrochemical cells in which electrons flow due to oxidation-reduction reaction .
Solution Summary: The author describes an electrochemical cell that has chemical energy stored in it that can be converted to electrical energy by means of flow of electrons due to oxidation-reduction reaction.
Definition Definition Chemical reactions involving both oxidation and reduction processes. During a redox reaction, electron transfer takes place in such a way that one chemical compound gets reduced and the other gets oxidized.
