Calculate the specific resistance of a 0.02 N solution of an electrolyte having equivalent conductance 103 `ohm^(-1)cm^(2)` `(g eq.)^(-1)`.

Text Solution

Verified by Experts

The correct Answer is:
485.4 ohm cm
`Delta_(E)=(1000xxk)/(C )or k=(Delta_(E)xxC)/(1000)`
`Delta_(E)=103" ohm"^(-1)cm^(2)(g eq)^(-1),C=0.02" N"`
`:." " k=(103" ohm"^(-1)cm^(2) cm^(-1)("g eq")^(-1)xx0.02("g eq"))/((1000" cm"^(3)))=2.06xx10^(-3)" ohm^(-1)cm^(=-1)`
Specific resistance `(rho)=(1)/(k)=(1)/(2.06xx10^(-3) ohm^(-1) cm^(-1))=485.4" ohm " cm`.
