Question

The effect of dilution on conductances shows:

• A. increase in conductivity
• B. increase in equivalent conductivity
• C. increase in molar conductivity
• D. decrease in conductance

Answer 1

Answer: (B), (C)

The correct options are
B increase in molar conductivity
C increase in equivalent conductivity

On dilution, the equivalent conductivity and the molar conductivity increases. This is because the degree of dissociation and the total number of ions increases. However the conductivity decreases as the number of ions per unit volume decreases.
