A constant current of 30 A is passed through an aqueous solution of $NaCl$ for a time of $1.00 h$ . What is the volume of $Cl_{2}$ gas at STP produced?

Options:

Answer:

Solution:

Due to electrolysis
$OH^{-}$ formed $= NaOH$ formed $= Zit$ $= \frac{E}{96500} \times i \times t$ $= \frac{40}{96500} \times 30 \times 1 \times 60 \times 60 = 44.77 g$ $= \frac{44.77}{40} = 1.12 mol$ $a_{2}$ formed $= \frac{1}{2} mol$ of $NaOH$ $= \frac{1.12}{2} = 0.56 mol$ $= 0.56 \times 22.4 L$ at $STP = 12.54 L$
