The conductivity of sodium Chloride at ...

The conductivity of sodium Chloride at `298K` has been determine at different concentrations and the results are given below `:`
`{:(Concentration(M):,0.001,0.010,0.020,0.050,0.100),(10^(2)xxk(Sm^(-1)):,1.237,11.85,23.15,55.53,1.06.74):}`
Calculate `wedge_(m)` for all concentrations and draw a plot between `wedge_(m)` and `c^(1//2)`. Find the value of `wedge_(m)^(@)`.

Text Solution

Verified by Experts

1 S `cm^(-1)=100" S "m^(-1)`
`(1" S "cm^(-1))/(100" S "cm^(-1))=1` (unit conversion factor)


`(AA)^(@)=`intercept on the `(AA)_(m)` axis=124.0 S `cm^(2)mol^(-1)` (on extrapotation to zero concentration).
