Question

How many coulombs of current will liberate 11.2 lit of chlorine at STP from a chloride solution ?

• A. 9650
• B. 19300
• C. 96500
• D. 1930

Answer 1

The correct option is C 96500

11.2 L of $C{l}_2$ at STP
$\therefore \text{moles of dichlorine}=\frac{11.2}{22.4}=0.5$
$2c{l}^{-}\to c{l}_2+2e^{-}$
1 mole of $c{l}_2$ gives 2 moles of $e^{-}$
$\therefore \text{moles of 1 electron}=0.5\times 2=1mole$
$chargeof\text{1 mole electron}=1\times 96500=96500C$
