NCERT Solutions for Class 12 Chemistry Chapter 3: 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.

FAQs on NCERT Solutions for Chemistry Class 12 Chapter 3

Q.1: From where can I download NCERT Class 12 Chemistry chapter 3 solutions?
Ans: Students can download the NCERT solutions for Electrochemistry from Embibe.

Q.2: Where can I solve Electrochemistry practice questions?
Ans: Students can solve CBSE Class 12 Chemistry chapter 3 questions for free on Embibe.

Q.3: How many exercises are there in Class 12 solutions for Chemistry chapter 3?
Ans: There are a total of 8 exercises with sub-units in Electrochemistry chapter of Class 12.

Q.4: What is corrosion in Class 12th Chemistry?
Ans: Corrosion is the term used to describe the process of the surface of metal objects getting covered by oxides (or) other salts of the metal. In corrosion, the metal is oxidised by losing electrons to oxygen, forming oxides. Corrosion is essentially an electrochemical process.

Q.5: What is galvanic cell in Chemistry?
Ans: Galvanic cells, also known as voltaic cells, are electrochemical cells in which spontaneous oxidation-reduction reactions produce electrical energy. The reaction may be split into two half-reactions. Half reactions separate the oxidation from the reduction, so each can be considered individually.
