Explanation
If cathode or anode is pulled out, no electrolysis will take place. The ions will start moving randomly.
Higher the oxidation potential ( or lower the reduction potential ) stronger the reducing agent .
1 F = Avogadro’s no. of electrons.
Faraday’s laws are related to equivalent weights
Amount of ion discharged does not depend upon resistance.
An electrolyte dissociates into ions when dissolved in suitable solvent.
When a lead storage battery is discharged, H2SO4 is consumed.
Cu + 2 Ag+ → Cu2+ + 2 Ag.
1 F = 96500 C.
Conductivity water has negligible conductance of its own.
See electrochemical series
Cl- ion is oxidized at anode.
See electrochemical series.
To deposit 1 g eq. of any element, 1 F is required.
O2 is produced at the anode.
Electrolysis of CuSO4 sol using Pt electrodes gives copper at cathode and oxygen at anode.
108 g Ag = 1 g eq. of Ag. It requires 1 F.
Lower the reduction potential, stronger is the reducing agent.
This is because zinc has higher oxidation potential than Ni, Cu and Sn.
Fuel cell converts chemical energy of H2 and O2 into electrical energy.
I2 is less reactive than Br2. Hence I2 cannot displace Br2 from KBr.
Oxidation takes place at anode viz (a).
