Redox Reactions Class 11 Notes Chemistry Chapter 8
By going through these CBSE Class 11 Chemistry Notes Chapter 8 Redox Reactions, students can recall all the concepts quickly. Redox Reactions Notes Class 11 Chemistry Chapter 8 → Reactions taking place in an electrochemical cell are redox reactions in nature. → In an electrochemical cell loss of free energy appears as electrical energy. → The reaction in an electrochemical cell is spontaneous in nature. → A salt bridge maintains the electrical neutrality of the two electrolytes in their half cells. → The e.m.f. of an electrochemical cell is E°cathode — E°anode cathode anode → According to the electronic concept, the loss of electron is oxidation, and the gain of the electron is reduced. → The oxidation number of free elements homo atomic molecules and also of the neutral molecule is zero. → Electrolysis is the migration of the ions of the electrolyte towards the oppositely charged electrode when the current is passed. → In an electrolytic cell, the redox reaction is non-spontan...
