Answer to Question #55471 in General Chemistry for John

Question #55471
Discuss the mechanism of a battery in the light of redox reactions.
Expert's answer
Batteries consist of electrochemical cells which store chemical energy for its later conversion to electrical energy.
Electrochemical reaction consists of 2 half-cell reaction (oxidation-reduction) linked via a semi permeable membrane. Each part of the cell contains a metal which acts as an electrode. One of the electrodes is called cathode, another electrode – anode. The side of the cell containing cathode is reduced (it gains electrons) acting as an oxidizing agent for anode.
