Q. A current of $16\ ampere$ flows through molten $NaCl$ for $10\ minute.$ The amount of metallic sodium that appears at the negative electrode would be
A) $0.23\ gm$
B) $1.15\ gm$
C) $2.3\ gm$
D) $11.5\ gm$
Explanation
(c) Amount of metallic sodium appearing,
$m = Zit = \left( \frac{A}{VF} \right)it = \left( \frac{23}{1 \times 96500} \right) \times 16 \times 10 \times 60 = 2.3\ gm$
