Question

100amps current is passed thought an acid cell for 6 hours. calculate the amount of hydrogen gas leberate at the electrode?​

Answer 1

Answer:

The reaction taking place at anode is:

71.0 g

2Cl

−

→

1 mole

71.0 g

Cl

2

+

2×96500 coulomb

2e

−

Q=I×t=100×5×60×60 coulomb

The amount of chlorine liberated by passing 100×5×60×60 coulomb of electric charge

=

2×9500

1

×100×5×60×60=9.3264 mole

Volume of Cl

2

liberated at NTP=9.3264×22.4=208.01 L
