Redox Electrochemistry
Conductivity is directly proportional to area of the vessel
Conductivity (unit Siemen’s S) is directly proportional to area of the vessel and the concentration of the solution in it and is inversely proportional to the length of the vessel then the unit of the constant of proportionality is
- S2 m2 mol-2
- S-2 m2 mol
- S m mol-1
- S m2 mol-1

- remove adsorbed oxygen from electrode surface
- produce high purity water
- generate heat
- create potential difference between the two electrodes
