Some possible Revision Notes for the chapter "Electrochemistry" in Class 12 Chemistry are:
1. Electrochemistry: Electrochemistry is the study of the relationship between electrical energy and chemical reactions.
2. Electrolytic Cells: Electrolytic cells use electrical energy to cause non-spontaneous reactions to occur. These cells require an external source of electrical energy to operate.
3. Galvanic Cells: Galvanic cells use spontaneous reactions to produce electrical energy. These cells do not require an external source of electrical energy to operate.
4. Electrodes: Electrodes are conductive materials that serve as the sites of non-spontaneous chemical reactions in electrolytic cells and spontaneous chemical reactions in galvanic cells.
5. Anode: The anode is the electrode in an electrochemical cell where oxidation takes place.
6. Cathode: The cathode is the electrode in an electrochemical cell where reduction takes place.
7. Standard Hydrogen Electrode (SHE): The Standard Hydrogen Electrode (SHE) is a reference electrode against which all other electrodes are measured.
8. Standard Reduction Potentials: Standard reduction potentials are a measure of the tendency of a half-reaction to occur as reduction.
9. Nernst Equation: The Nernst equation is used to determine the potential of an electrode under non-standard conditions.
10. Electrolysis: Electrolysis is the process of using electrical energy to cause chemical reactions to occur in solution.
11. Faraday's Laws of Electrolysis: Faraday's first law states that the amount of a substance produced at an electrode during electrolysis is directly proportional to the amount of electrical charge passed through the electrode. Faraday's second law states that the amounts of different substances produced at electrodes during electrolysis are proportional to their respective chemical equivalent weights.
12. Corrosion: Corrosion is the process by which metals are oxidized by chemical reactions with their environment.
13. Electroplating: Electroplating is the process of using electrolysis to deposit a thin layer of one metal onto another metal. This is commonly used to coat metals with a more desirable metal, such as gold or silver.
