Question

Calculate the amounts of Na and chlorine gas produced during the electrolysis of fused NaCl by the passage of 1 ampere current for 25 minutes. Molar masses of Na and chlorine gas are 23g${mol}^{-1}$ and 71g${mol}^{-1}$ respectively.

Answer 1

For Na, we have

$w=\frac{23\ast 1\ast 25\ast 60}{96500}$

$w=0.357g$

for chlorine, we have

$w=\frac{71\ast 1\ast 25\ast 60}{2\ast 96500}$

$w=0.55g$
