Question
Q what vol. of O2 OBTAINED AT ANODE AT STP IF Aq SOLn OF CuSO4 IS ELECTROLYSED BY PASSG 100A CURRENT FOR 60 MIN? ANS 20.89L
Joshi sir comment
Total charge flown in the circuit = 100*60*60 = 360000 coulomb
so no of faradays of electricity = 360000/96500 = 3600/965 = 3.73 F
so amount of O2 = 3.73*5.6 = 20.89 litre
Here 5.6 litre is eq. volume corresponding to 8 gm. of O2
