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
$\mathrm{W}=\frac{\mathrm{E}}{96500} \times \mathrm{Q}$
$\mathrm{W}=\frac{\mathrm{E}}{96500} \times \mathrm{Q}$
$710=\frac{35.5}{96500} \times \mathrm{Q}$
$\mathrm{Q}=1930000=1.93 \times 10^{6}\,\mathrm{C}$
