Variation Of Molar Conductivity With Concentration

Define limiting molar conductivity in terms of Kohlrausch law of independent migration of ions.

Define the term limiting molar conductivity. How can you determine limiting molar conductivity?

$0.05 \mathrm{M}$ of an electrolyte offered a resiatance of $31.2 \mathrm{ohm}$ in a conductivity cell having a cell constant of $0.38 {\mathrm{cm}}^{-1}$. Calculate the molar conductivity of the solution.

Give the mathematical equation which gives the variation of molar conductanctivity ${\mathrm{\Lambda }}_{\mathrm{m}}$, with the molarity (c) of the solution.

The molar conductivity of $0.025 \mathrm{m}\mathrm{o}\mathrm{l} {\mathrm{L}}^{-1}$ methanoic acid is $46.1 \mathrm{S} \mathrm{c}{\mathrm{m}}^2 \mathrm{m}\mathrm{o}{\mathrm{l}}^{-1}.$ Calculate its degree of dissociation and dissociation constant. Given ${\mathrm{\lambda }}^0\left({\mathrm{H}}^{+}\right)=349.6 \mathrm{S} \mathrm{c}{\mathrm{m}}^2 \mathrm{m}\mathrm{o}{\mathrm{l}}^{-1}$ and
 ${\mathrm{\lambda }}^0\left({\mathrm{HCOO}}^{-}\right)=54.6 \mathrm{S} {\mathrm{cm}}^2 {\mathrm{mol}}^{-1}.$

The following curve is obtained when molar conductivity,${\mathrm{\Lambda }}_{\mathrm{m}}$ is plotted against the square root of concentration, ${\mathrm{C}}^{1/2}$ along $\mathrm{B}$ and $\mathrm{A}$-axis respectively for the two electrolytes $\mathrm{A}$ and $\mathrm{B}$. Account for the increase in ${\mathrm{\Lambda }}_{\mathrm{m}}$ for the electrolytes $\mathrm{A}$ and $\mathrm{B}$ with dilution.

The molar conductance of 0.001 M acetic acid is ${\text{50 ohm}}^{-1}{cm}^2{mol}^{-1}$. The maximum value of molar conductance of acetic acid is ${\text{250 ohm}}^{-1}{cm}^2{mol}^{-1}$. What is the degree of dissociation $\left(\alpha \right)$ of acetic acid ?
