Question

Molar conductivities at infinite dilution of $N a C l$ , $H C l$ and $C H_{3} C O O N a$ are 126.4, 425.9 and 91.0 $S c m^{2} m o l^{- 1}$ respectively. Molar conductivity for $C H_{3} C O O H$ will be:

Solution

$C H_{3} C O O N a + H C l ⟶ N a C l + C H_{3} C O O H$
$\Rightarrow 91 + 425.9 = 126.4 + x$
$\Rightarrow x = 516.9 - 126.4$
$= 390.5 S c m^{2} m o l^{- 1}$
