Question

The molar conductance of a solution of a weak electrolyte with dilution.

• A. increases
  
• B. decreases
• C. remains constant

Answer 1

The correct option is A increases


On dilution, the degree of dissociation of a weak electrolyte will increase. Since the molarity decreases with dilution, the numerator increases, denominator decreases and hence, the molar conductivity increases sharply.
