Read the passage carefully and answer the questions.
Electrochemistry is the study involving two types of processes. One type involves the production of electricity from the energy released during a spontaneous chemical reaction. Galvanic cells like Daniel cells are used to produce electricity from the redox reaction. Nernst equation of a galvanic cell gives the relation between the standard cell potential and the concentration of the species involved in the redox reaction. The second type of study involves the cells in which electrical energy is used to bring about the chemical reactions in a non-spontaneous process. The conductance of electrolytic solution depends on many factors including the nature of the electrolyte and the dimensions of the electrolytic cell.
Faraday's laws of electrolysis are related to:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Equivalent mass of electrolyte
Faraday’s laws give the quantitative relation between the charge passed and the amount of substance discharged at an electrode. By the first law, the mass deposited is proportional to the charge, \( m = Z\,Q \). By the second law, the same charge liberates different substances in amounts proportional to their chemical equivalent weights (atomic mass divided by the number of electrons needed per ion):
\( \displaystyle \frac{m_1}{m_2} = \frac{E_1}{E_2} \)
So Faraday’s laws are related to the equivalent mass of the electrolyte.
