Q8 / 150 · MHT CET 2007 · Chemistry

The amount of silver deposited on passing $2 \mathrm{~F}$ of electricity through aqueous solution of $\mathrm{AgNO}_{3}$ is

  • A
    $54 \mathrm{~g}$
  • B
    $108 \mathrm{~g}$
  • Correct answer
    C
    $216 \mathrm{~g}$
  • D
    $324 \mathrm{~g}$

Solution

According Faraday law's $$ \begin{array}{l} m=z \times Q=\frac{E \times Q}{96500} \\ m=\frac{108}{96500} \times 2 \times 96500=216 \mathrm{~g} \end{array} $$

Hence, the correct answer is option: 'C'.
