Which of the following electrolytic solutions has the least specific conductance?
- A \(0.02 \mathrm{~N}\)
- B \(0.2 \mathrm{~N}\)
- C \(2 \mathrm{~N}\)
- D \(0.002 \mathrm{~N}\)
Answer & Solution
Correct Answer
(D) \(0.002 \mathrm{~N}\)
Step-by-step Solution
Detailed explanation
Specific conductance is defined as the conductance of one centimeter cube (cc) of the solution of an electrolyte. Upon dilution, the concentration of ions per cc decreases, so the specific conductance falls.
Thus, specific conductance \(\propto\) concentration of electrolytes, hence specific conductance is least for the solution of \(0.002 \mathrm{~N}\) concentration.
Thus, specific conductance \(\propto\) concentration of electrolytes, hence specific conductance is least for the solution of \(0.002 \mathrm{~N}\) concentration.
