$Just \;to\;add\;a\;little\; more\;as\;I\;had \;read\;in \;my \;Arihant\;text\; book \;:$ :

$When\;concentration\;is\;low\;the\;molar\;conductivity\;of\;strong\;elctrolytes\;is\;found\;to\;obey$

$the\;Debye\;Huckel\;Osnager\;equation :$

$\wedge_m = \wedge_m^{\infty}\; - \;[ A + B\wedge_m^{\infty}] \sqrt{c}$

$where \;A\;and\;B\;are\;called\;Debye-Huckel \;constants$

$A \;= 82.4/\sqrt(DT) \;\eta$

$B\; =\;8.20\;.\;10^{5} / {DT}^{3/2}$

$where \;D\;and\;\eta\;are\;the\;dielectric\;constant\;and\; coefficient\;of \;viscosity$ $of\;the\;medium\;at\;temperature\;T\;and\;C\;is\;molar\;concentration$

$Rest\;is\;perfect\;;infact\;you \;do\;not\;need\;so\;much\;of\;details.$

From J.R.R. Tolkien's 'The Lord of the Rings':

All that is gold does not glitter
Not all who wander are lost
The old that is strong does not wither,
Deep roots are not reached by frost.
From ashes a fire shall be woken
From shadows a light shall spring
Renewed shall be blade that's broken
The crown less again shall be king.
