FAQs on Maharashtra Board Class 12 Solutions for Chemistry Chapter 5 Electrochemistry - PDF
1. What is Electrochemical Cell?
In electrochemistry, redox reactions that occur spontaneously transform chemical energy into electrical energy. A non-spontaneous chemical reaction can likewise happen in the opposite manner by applying electricity. Electrochemical cells are the pieces of machinery used to carry out these inter-conversions.
2. What are the types of Electrochemical Cell?
Electrochemical Cell is of Two Types:
Galvanic Cell
With the aid of a redox reaction, the galvanic cell transforms chemical energy into electrical energy, or electricity. Separate chambers are used for the oxidation and reduction processes.
Electrolytic Cell
In an electrolytic cell, electrical energy is changed into chemical energy. In this case, an electrolytic solution comprising cations and anions is used to immerse the electrodes.
3. What is Faraday's Law of Electrolysis?
In 1834, Faraday presented the law of electrolysis, which describes the link between the amount of electric charge that passes through an electrolyte and the amount of substance that is deposited at the electrodes.
4. What does the Faraday's First Law says?
The amount of substance deposited when an electric current is carried through an electrolyte is proportional to the amount of electric charge passed through the electrolyte.
