Explanation:

Factors affecting ionic conductance

Nature of the Electrolyte:  There are weak electrolytes and strong electrolytes, strong electrolytes get ionized completely in the solution whereas weak electrolytes do not. An example of a strong electrolyte is KNO3 and an example of a weak electrolyte is CH3COOH.

Temperature: Temperature is also one of the main factors as the ions should dissolve in the solution at a given temperature. So, at higher temperatures, the solubility is more.

Nature of the solvent:  The type of solvent is the fifth factor that affects electrolytic conductivity. Higher the polarity of the solvent type, the higher the conductivity.
