Q. On passing 0.5 F electricity through molten sodium chloride, sodium deposited at cathode will be
A) 29.25 g
B) 11.50 g
C) 58.50 g
D) 0.00 g
Explanation
(b)
We know that 1 Faraday charge liberates one gram- equivalent of a metal, hence 0.5 F charge will liberate
$= \ 0.5\ \times \ 23\$
= 11.50 g of sodium (E = 23)
