List of top Chemistry Questions on Conductance asked in AP EAPCET

The \(\Lambda_m\) (on y-axis) of \(NaCl\) and \(CsCl\) was plotted against \(\sqrt{c}\) \((c=\text{concentration on x-axis})\). Identify the correct figure for these electrolytes. \[ \Lambda_m=\Lambda_m^\circ-K\sqrt{c} \] Given: \[ \lambda^\circ_{Na^+}=50\; S\,cm^2\,mol^{-1} \] \[ \lambda^\circ_{Cs^+}=77\; S\,cm^2\,mol^{-1} \]
The conductivity of \(0.001\ \mathrm{M}\) acetic acid is \(5\times10^{-5}\ \mathrm{S\,cm^{-1}}\). If the molar conductivity of acetic acid solution at infinite dilution is \(390.5\ \mathrm{S\,cm^2\,mol^{-1}}\), what is the degree of dissociation?
Resistance of a conductivity cell filled with \(0.1 \text{ mol L}^{-1}\) NaCl is \(100 \, \Omega\). If the resistance of the same cell when filled with \(0.02 \text{ mol L}^{-1}\) NaCl solution is \(258 \, \Omega\), then the conductivity of \(0.02 \text{ mol L}^{-1}\) NaCl solution is:
\[ \text{(Conductivity of }0.1 \text{ mol L}^{-1}\text{ NaCl} = 1.29 \, \text{S m}^{-1}) \]
