Solution

Q.
For strong electrolyte $Λ_{m}$ increases slowly with dilution and can be represented by the equation

$Λ_{m} = Λ_{m} ° - A c^{1 / 2}$

Molar conductivity values of the solutions of strong electrolyte AB at 18°C are given below :

c $(m o l L ⁻ ¹)$

0.04

0.09

0.16

0.25

$Λ ₘ (S c m ² m o l ⁻ ¹)$

96.1

95.7

95.3

94.9

The value of constant A based on the above data in $[{S c m}^{2} {mol}^{- 1} / {({mol L}^{- 1})}^{1 / 2}]$ unit is_______. [2026]

Ans.
4
