The equivalent conductivity of

\mathrm{KCl}

at infinite dilution is 130

{\rm{mho {\kern 1pt} {\kern 1pt}c}}{\mathrm{m}^2}{\kern 1pt} {\kern 1pt}\mathrm{e}{\mathrm{q}^{ - 1}}

. The transport number of

\mathrm{C}{\mathrm{l}^ - }

ion in

\mathrm{KCl}

at the same temperature is 0.505. The transport number of

{\mathrm{K}^ + }

ion is :

View answer and explanation

Correct option: A

0.495

Option A (0.495) is correct because the sum of the transport numbers of the cation and anion in an electrolyte solution must equal 1.
