MCQ

The unit of equivalent conductivity is

A
$ohm \,cm$
✓
$oh{m^{ - 1}}c{m^2}\,{(gm\,\;equivalent)^{ - 1}}$
C
ohm $c{m^2}\,(gm\,\,equivalent)$
D
$S\,c{m^{ - 2}}$

✓

Answer

Correct option: B.

$oh{m^{ - 1}}c{m^2}\,{(gm\,\;equivalent)^{ - 1}}$

b
$A _{\text {eq }}= k \times 1000 / c = k \times 100 / C$

where $A _{ eq }=$ equivalent conductance

$C =$ concentration in $eq / L$

$\therefore$ Units of $A _{\text {eq }}$ are $ohm ^{-1} cm ^2\left( g - eq ^{-1}\right)$
