Lambda HCl ∞=426.2 (i) Lambda AcONa ∞=91.0 (ii) Lambda NaCl ∞=126.5 (iii) Lambda AcOH ∞=( i )+( ii)-(iii) =[426.2+91.0-126.5]=390.7

Q.
Calculate $Λ_{H O A c}^{\infty}$ using appropriate molar conductances of the electrolytes listed above at infinite dilution in $H_{2} O$ at $2 5^{\circ} C$

$217.5$

$390.7$

$552.7$

$5172$

$Λ_{H Cl}^{\infty} = 426.2$
(i) $Λ_{A c ON a}^{\infty} = 91.0$
(ii) $Λ_{N a Cl}^{\infty} = 126.5$
(iii) $Λ_{A c O H}^{\infty} = (i) + (ii) - (iii)$
$= [426.2 + 91.0 - 126.5] = 390.7$
