Write the formula to calculate conductivity by using a conductivity cell.

Which of the following cannot be used as a standard solution for the determination of the cell constant of a conductivity cell?

The electronic conductance does not depend on . . . . . . .

Provide the graph of $\Lambda_{m}$ versus $c^{1/2}$ for aqueous solutions of strong and weak electrolytes,and clarify their differences and uses.

Equivalent conductivity at infinite dilution for sodium potassium oxalate $[(COO^{-})_{2} Na^{+} K^{+}]$ will be (given molar conductivities of oxalate,$K^{+}$ and $Na^{+}$ ions at infinite dilution are $148.2$,$50.1$,and $73.5 \ S \ cm^{2} \ mol^{-1}$ respectively).

The equivalent conductances of two strong electrolytes at infinite dilution in $H_2O$ (where ions move freely through a solution) at $25 ^\circ C$ are given below:
$\Lambda _{CH_3COONa}^o = 91.0 \ S \ cm^2 / equiv.$
$\Lambda _{HCl}^o = 426.2 \ S \ cm^2 / equiv.$
What additional information/quantity one needs to calculate $\Lambda ^o$ of an aqueous solution of acetic acid?
