Question

$20$g of chlorine are evolved in $6$ hour from sodium chloride solution by the current of:

Answer 1

$\because$ w = z.i.t $\Rightarrow$ 20 = $\left(\frac{35.5}{1}\frac{\times i\times 6\times 3600}{\times 96500}\right)$

$\therefore$ $i=2.51Amp$

Note: $\left\{\begin{array}{c}{n}_f({Cl}^{-}\to {Cl}_2)=1\\ AtWt\left({Cl}_2\right)=35.5\end{array}\right\}$
