Question

The unit of equivalent conductivity is

• A. ohm cm
• B. $ohm ^{-1} cm ^{2}( g - eq )^{-1}$
• C. $ohm^{-1} \, cm^{+2} (g\, {\text{equivalent}})^{-1}$
• D. $S\, cm^2$

Answer 1

Answer: (B)

$A _{ e q }= k \times 1 0 0 0 / c = k \times 1 0 0 / C$ where $A _{ eq }=$ equivalent conductance $C =$ concentration in eq/L $\therefore $ Units of $A _{\text {eq }}$ are ohm $^{-1} c m ^{2}\left( g - e q ^{-1}\right)$
