Points to Remember

Students can find the important points to remember from NCERT Class 12 Chemistry Chapter 3, as mentioned below. Going through the points before final exams helps students to have a quick revision of Chapter 3 Chemistry.

Electrochemical Cell: A device that converts chemical energy into electrical energy.
Anode: In electrochemical cells, the anode is the electrode at which oxidation takes place. It is the negative terminal.
Cathode: In electrochemical cells, the cathode is the electrode at which reduction takes place. It is the positive terminal.
EMF of the cell or Ecell = Ecathode −Eanode .
Thermodynamic Efficiency of Cell: It is the ratio of Gibb’s energy change to the enthalpy change of the cell reaction η = ΔG/ΔH.
Electrochemical Series: Arrangement of various elements and electrode reactions in the increasing order of their reduction potentials.
Electrolyte: A substance that dissociates in solution to produce ions and hence conducts electricity in a dissolved state or molten state.
Molar Conductivity: Conductance of a solution containing one mole of the electrolyte, placed between two parallel electrodes one cm apart.

Topics and Sub-Topics

Below is the list of important topics included in Class 12 Chemistry Chapter 3 Electrochemistry.

Sr. No	Name of the Topic	Description
1	Electrochemical Cells	A device that generates a potential difference between electrodes by chemical reactions is called an electrochemical cell. It comprises two electron conductors which are separated by an ionic conductor and are linked by an electron conductor. The two metallic electrodes are dipped in the electrolytic solution. The important component of this cell is an ionic conductor.
2	Galvanic Cells	Galvanic cell – In a galvanic cell, spontaneous redox reaction, the chemical energy is converted into electrical energy. It is also called voltaic cell or Daniel cell.
3	Electrode Potential and Standard Electrode Potential
4	Nernst Equation
5	Relationship between Electrode Potential, Gibb’s Free Energy and Equilibrium Constant
6	Electrolytic and Metallic Conduction
7	Conductance in Electrolytic Solutions
8	Kohlrausch’s Law and Its Application
9	Electrolytic Cells and Electrolysis	Electrolytic cell – In an electrolytic cell, the nonspontaneous redox reaction is carried out by electrical energy.
10	Batteries
11	Fuel Cells
12	Corrosion and Its Prevention
