Question

Which of the following conditions are satisfied when the electrolytic solutions are infinitely dilute?

(a) Electrolyte is 100% dissociated

(b) Interionic effects increase

(c) Conductance is infinite at infinite dilution

(d) Molecules continue to exist in solution

The question was posed to me in an interview for internship.

This question is from Conductance of Electrolytic Solutions in chapter Electrochemistry of Chemistry – Class 12

Answer 1

Right option is (a) Electrolyte is 100% dissociated

To elaborate: At infinite dilution, even weak electrolytes behaves like strong electrolytes and undergo complete ionization. Hence, the electrolyte is 100% dissociated. Also, at infinite dilution, the ions are far apart and interionic effects disappear.
