Assertion (A): The charge on one mole of electrons is one Faraday.
Reason (R): The quantity of current required to deposit one mole of \(\mathrm{Mg}\) from \(\mathrm{Mg}^{2+}\) electrolyte solution is two Faradays.
The correct answer is
- A Both (A) and (R) are correct and (R) is the correct explanation of (A).
- B Both (A) and (R) are correct but (R) is not the correct explanation of (A).
- C (A) is correct but (R) is not correct.
- D (A) is not correct but (R) is correct.
Answer & Solution
Correct Answer
(A) Both (A) and (R) are correct and (R) is the correct explanation of (A).
Step-by-step Solution
Detailed explanation
The quantity of current required to deposit one mole of \(\mathrm{Mg}\) from \(\mathrm{Mg}^{2+}\) electrolyte solution is two Faradays. \[ \mathrm{Mg}^{2+}+2 e^{-} \longrightarrow \mathrm{Mg} \] \(\therefore\) Quantity of electricity required \(=2 \mathrm{~F}\) Thus, two mole of…
