Second Law: The mass of substance produced in electrolysis directly proportional to its equivalent mass.
W1 / E1 = W2 / E2 = W3 / E3...
Third Law: The mass of a substance produced in electrolysis is directly proportional to the number of electrons per mole needed to cause desired change in oxidation state.
Conductivity
When voltage is applied to the electrodes immersed into an electrolyte solution, ions of electrolyte move, and thus, electric current flows through the electrolytic solution. The electrolytic solution and the metal conductors exhibit resistance to the passage of the current; both of which obey Ohm's law.
The reciprocal of resistance is called electrical conductance. The unit of electrical conductance is Siemens (S) or ohm-1 or mho.
If a solution is placed between two parallel electrodes having cross sectional area A and distance L apart then the resistance is given by
R = 1 / C
ρ (called 'rho') is known as resistivity. Its reciprocal gives the conductivity of the solution, which is denoted by κ (called 'kappa'). Its unit is Siemens/meter.
Κ = 1 / R * L / …show more content…
Conclusion
On heating a solution, it is known that viscosity gradually decreases, with decrease in viscosity, the speed and movement of the ions increases. In other words, the conductance of the electrolyte increases with increases in temperature. Hence, the result of the experiment agrees with reasoning.
Precautions
Variation of resistance due to one of the factors should be kept constant.
The electrodes used in each case should always be kept parallel to each
