Class 12 Chemistry Chapter 3: Electrochemistry – Important Topics

Important topics of Class 12 Chemistry Chapter 3 Electrochemistry includes the following.

Electrochemistry deals with the study of electricity in chemistry involving electrodes, electrolysis, solutions and solvents. This mechanism is commonly seen in Electrochemical cells. There are two common types of electrochemical cells.

Galvanic Cell: In this, chemical energy is converted to electrical energy. It is also known as voltaic cell. Here, the anode is negatively charged and cathode is positively charged.

Electrolytic Cell: In this, electrical energy is converted to chemical energy. Here, the cathode is negatively charged and anode is positively charged.

Standard Electrode Potential is the standard EMF of the cell. The potential difference between the electrode and electrolyte is known as the potential of electrode and at unit concentration.

E⁰_Cell = E⁰_{red, Cathode} – E⁰_{red, Anode}

Nernst equation is establishes the relation between the cell potential of an electrochemical cell, the standard cell potential, temperature, and the reaction quotient.

\(E_{cell} = E^0 _{cell} - \frac{RT}{nF}ln Q\)
