ELECTROCHEMISTRY
Electrochemical Cells
In our day to day lives we use different appliances powered by domestic
electricity and as well as appliances operated by electrochemical cells

...
Many oxidation-reduction reactions occur spontaneously, giving off energy
...
Cu+2 (aq) + Zn (s) -------> Cu(s) + Zn+2 (aq)
The zinc metal slowly "dissolves" as its oxidation produces zinc ions which enter
into solution
...
The energy produced in this reaction is quickly dissipated as heat, but it
can be made to do useful work by a device called, an electrochemical cell
...
An electrochemical cell is composed to two compartments or half-cells, each
composed of an electrode dipped in a solution of electrolyte
...
An electrochemical cell is a device capable
of either generating electrical energy from
chemical reactions or facilitating chemical
reactions through the introduction of electrical
energy
...
5 volt cell meant for consumer use
