Among the following,the plot that correctly represents the conductometric titration of $0.05 \ M \ H_2SO_4$ with $0.1 \ M \ NH_4OH$ is

$A$ conductivity cell containing $5 \times 10^{-4} \ M \ NaCl$ solution develops a resistance of $14000 \ \Omega$ at $25^{\circ} C$. Calculate the conductivity of the solution if the cell constant is $0.84 \ cm^{-1}$.

An increase in equivalent conductance of a strong electrolyte with dilution is mainly due to

The ionic conductance of the following cations in a given concentration is in the order:

If the distance between two $Pt$ electrodes is $2 \, cm$,the cross-sectional area is $4.0 \, cm^2$,and the resistance is $25 \, \Omega$,find the molar conductivity of a $0.5 \, M$ solution.

At $25^oC$,the molar conductance of a $0.1 \ M$ aqueous solution of ammonium hydroxide is $9.54 \ \Omega^{-1} \ cm^2 \ mol^{-1}$ and at infinite dilution,its molar conductance is $238 \ \Omega^{-1} \ cm^2 \ mol^{-1}$. The degree of ionization of ammonium hydroxide at the same concentration and temperature is ........... $\%$.
