Q. The specific conductance ($\kappa$) of an electrolyte of 0.1 N concentration is related to equivalent conductance ($\Lambda$) by the following formula
A) $\Lambda = \kappa$
B) $\Lambda = 10\kappa$
C) $\Lambda = 100\kappa$
D) $\Lambda\ = 10000\kappa$
Explanation
(d)
Equivalent conductance (⋀) = specific conductance $(\kappa) \times \ \phi\$
$where,\ \phi\ = \ volume\ in\ {cm}^{3}$ containing 1 g equivalent of electrolyte
g equivalent is dissolve in $= \ {1000\ cm}^{3}\$
1 g equivalent is dissolve in $= \ \frac{1000}{0.1}\ {cm}^{3}$
$= \ 10000{cm}^{3}\$
So, $\bigwedge\ = \ 10000\ \kappa$
