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 $ohm ^{-1} cm ^2\left( g - eq ^{-1}\right)$
