Question

For strong electrolytes the plot of molar conductance vs \( \sqrt{C} \) is

• A. parabolic
• B. linear
• C. sinusoidal
• D. circular

Hint:

For strong electrolytes, molar conductance decreases linearly with the square root of concentration.

Answer 1

The Correct Option is B

Step 1: Relationship between molar conductance and concentration.
For strong electrolytes, the molar conductance is inversely proportional to the square root of concentration, resulting in a linear relationship when plotted against \( \sqrt{C} \).

Step 2: Conclusion.
Thus, the correct answer is option (B).

Final Answer: \[ \boxed{\text{(B) linear}} \]
