Specific conductance of 1 M KNO(3) solut...

Specific conductance of 1 M `KNO_(3)` solution is observed to be `5.55 times 10^(-3)` mho `cm^(-1)`. What is the equivalent conductance of `KNO_(3)` when one litre of the solution is used?

Text Solution

Verified by Experts

Specific conductance `kappa=4.23xx10^(-4)"mho.cm"^(-1)`
`lambda_(C )=(kappa1000)/(C )=(4.23xx10^(-4)xx1000)/(0.04)`
`=10.575"mho.cm"^(2).eq^(-1)`.
`alpha=0.0612=(lambda_(C ))/(lambda_(oo))=(10.575)/(lambda_(oo))`
`therefore lambda_(oo)="172.79 mho. cm"^(2)."gm. equiv."^(-1)`.
