Which of the following statements is incorrect
The specific conductance of a saturated $AgCl$ solution is found to be $1.86\times {{10}^{-6}}\,S\,c{{m}^{-1}}$ and that for water is $6.0\times {{10}^{-8}}\,S\,c{{m}^{-1}}$. The solubility of AgCl is $({{\Lambda }_{0}}=137.2\,S\,equi{{v}^{-1}}\,c{{m}^{2}})$
Aniline hydrochloride $({{C}_{6}}{{H}_{5}}N{{H}_{3}}Cl)$ is a salt of a weak base and strong acid. The hydrolysis equilibria ${{K}_{h}}=\frac{{{h}^{2}}C}{(1-h)}$. On the basis of conductivity, h is given by (where $\Lambda$, ${{\Lambda }_{1}},\,{{\Lambda }_{2}}$ are equivalent conductance of hydrolysed salt, unhydrolysed salt and HCl respectively, Kh = hydrolysis constant, C = concentration of ${{C}_{6}}{{H}_{5}}N{{H}_{3}}Cl$ and h = degree of hydrolysis).
$500 mL$ of an aqueous solution contains $40.1 mol$ of the solute $AB$; if its specific conductance is $x Sc{{m}^{-1}}$, its molar conductance will be…. $S\,c{{m}^{2}}\,mo{{l}^{-1}}$
