For which electrolyte the molar conductivity at infinite dilution can not be obtained graphically?
- A \(\mathrm{HNO}_3\)
- B \(\quad \mathrm{H}_2 \mathrm{SO}_4\)
- C \(\mathrm{CH}_3 \mathrm{COOH}\)
- D KCl
Answer & Solution
Correct Answer
(C) \(\mathrm{CH}_3 \mathrm{COOH}\)
Step-by-step Solution
Detailed explanation
The molar conductivity of weak electrolyte like \(\mathrm{CH}_3 \mathrm{COOH}\) does not vary linearly with square root of concentration as shown in the figure. As a result, \(\Lambda_0\) cannot be determined by extrapolation method graphically unlike strong electrolytes.
