Question

Amount of electricity that can deposit 108 gm of silver from AgNO₃ solution is.

• A. 1 ampere
• B. 1 coulomb
• C. 1 faraday
• D. None of the above

Answer 1

Answer: (C)

1 faraday

Answer 2

$Ag^{+} + e^{-} \rightarrow Ag;E_{Ag} = \frac{AtomicMass}{1} = 108$

Number of faraday $= \frac{W_{Ag}}{E_{Ag}} = \frac{108}{108} = 1$.
