Important topics for NCERT Exemplar Class 12 Chemistry Solutions Chapter 3 – Electrochemistry

  • Oxidation: This is the process that involves the loss of electrons.
  • Reduction: This is the process that involves a gain in electrons.
  • Direct redox reaction: This process involves both oxidation and reduction reactions taking place in the same vessel. During a direct redox reaction, chemical energy gets converted into heat energy.
  • Indirect redox reaction: During this process, the oxidation and reduction take place in different vessels. The chemical energy gets converted into electrical energy. The device using which this change takes place is known as an electrochemical cell.
  • Salt bridge: The function of a salt bridge is to maintain electrical neutrality. It allows the flow of electric current by completing the electrical circuit.
  • Types of electrode potential: The two types of electrode potential are as follows  –
    1.     Oxidation potential – It is the tendency of an electrode to get oxidized or lose electrons.
    2.     Reduction potential – It is the tendency of an electrode to get reduced or gain electrons.
  • SHE: SHE or standard hydrogen electron comprises a platinum wire, which is sealed in a glass tube and carries a platinum oil at one end.
  • There are several other significant topics and concepts in the given chapter, which you need to go through thoroughly.
