For which electrolyte the molar conductivity at infinite dilution can not be obtained graphically?
For which electrolyte the molar conductivity at infinite dilution can not be obtained graphically?
$\mathrm{HNO}_3$
$\quad \mathrm{H}_2 \mathrm{SO}_4$
$\mathrm{CH}_3 \mathrm{COOH}$
KCl
Solution
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.
