Chapter 3 Electrochemistry talks about electrochemical cells, Nernst equation, Batteries, Corrosion, etc. Electrochemical cells are of two types: Galvanic cell and the electrolytic cell. Fuel cells and Batteries are very beneficial forms of a galvanic cell. There are two main classifications of batteries. They are primary batteries and secondary batteries. Primary batteries die after a period of time and are not reusable as it cannot be recharged. Whereas, secondary batteries can be recharged and are reusable.

Frequently asked Questions on CBSE Class 12 Chemistry Notes Chapter 3: Electrochemistry
What is a ‘Galvanic cell’?
Galvanic cell is an electrochemical cell in which an electric current is generated from spontaneous oxidation-reduction reactions.
What is ‘EMF’?
Electromotive force is equal to the terminal potential difference when no current flows.
What is ‘Reduction potential’?
Reduction potential is the a tendency of a chemical species to be reduced by gaining an electron.
