Given, $\lambda_{\left(\mathrm{Ag}^{+}\right)}^{\circ}=6 \times 10^{-3} \mathrm{Sm}^2 \mathrm{~mol}^{-1}, \lambda_{\left(\mathrm{Br}^{-}\right)}^{\circ}=8 \times 10^{-3} \mathrm{Sm}^2 \mathrm{~mol}^{-1}, \lambda_{\left(\mathrm{NO}_{\mathrm{j}}\right)}^{\circ}=7 \times 10^{-3} \mathrm{Sm}^2 \mathrm{~mol}^{-1}$.
$[Br^-] = [Cl^-] = [CO_3^{2-} ] = [AsO_4^{3-}] = 0.1\,M$.
Which compound will precipitate with lowest $[Ag^+]$ ?
