Q.

Identify the factor from the following that does not affect electrolytic conductance of a solution.                 [2024]

1 The nature of solvent used.  
2 Concentration of the electrolyte.  
3 The nature of the electrode used.  
4 The nature of the electrolyte added.  

Ans.

(3)

1.     HCl in water is almost 100 percent ionized whereas HCl in CCl4 is almost unionised. The two solutions have different conductance. Hence conductance depends upon nature of solvent.

2.      For strong as well as weak electrolyte, conductance increases with dilution.

3.      Conductance does not depend upon nature of electrode used.

4.      For same concentration, strong electrolyte has more conductance than weak electrolyte.
