How many gram...

Question

How many grams of $C l_{2} (g)$ can be produced by the electrolysis of molten $N a C l$ with a current of $5.5 A$ for $25$ min?

Open in App

Solution

$2 {C l}^{(-)} + 2 e^{-} ⟶ {C l}_{2}$
Moles of $F = \frac{c h a n g e}{96500} = \frac{I \times t}{96500} = \frac{5.5 \times 25 \times 6}{96500}$
$= 0.085 m o l e s$
2 mol $F \to 71 g$
$0.085 m o l \to \frac{71}{2} \times 0.085 = 3.017 g$
