MCQ

Electricity required for liberating $710\, g$ of $Cl_2(g)$ by electrolyzing a concentrated solution of $NaCl$ will be

A
$1.93 \times {10^5}\,C$
✓
$1.93 \times {10^6}\,C$
C
$9.65 \times {10^6}\,C$
D
$9.65 \times {10^5}\,C$

✓

Answer

Correct option: B.

$1.93 \times {10^6}\,C$

b
$\mathrm{W}=\frac{\mathrm{E}}{96500} \times \mathrm{Q}$

$710=\frac{35.5}{96500} \times \mathrm{Q}$

$\mathrm{Q}=1930000=1.93 \times 10^{6}\,\mathrm{C}$
