Electrochemical Battery

An electrochemical battery is a device powered by oxidation and reduction reactions that are physically separated. So that the electrons must travel through a wire from the reducing agent to the oxidizing agent.

The reducing agent loses electrons and is oxidized in a reaction that takes place at an electrode is called the anode. The oxidizing agent gains electrons and is reduced in a reaction that takes at an electrode is called the cathode.

To maintain a net zero charge in each compartment, there is a limited flow of ions through a salt bridge.
For example, in a car battery the reducing agent is oxidized by the following reaction, which involves a lead ( Pb ) anode and sulfuric acid ( H2SO4). Lead sulfate ( PbSO4 ), protons ( H ), and electrons ( e) are produced.

At the cathode, the below reaction occurs :

PbO2+H2SO4+2H++2e PbSO_4+2H_2O$
At the anode, the below reaction occurs :

Pb+H2SO4PbSO4+2H++2e
