The values of `Lambda_(eq)^(@)` of KI and KCl solutions are 150.30 and `"149.90 ohm"^(-1)."cm"^(2)."g-equiv"^(-1)` respectively. If `lambda^(@)` value of `Cl^(-)` ion is `"76.34 ohm"^(-1)."cm"^(2)."g - equiv"^(-1)`, find the value of `lambda_(I^(-))^(@)`.

Text Solution

Verified by Experts

`Lambda_("KI")^(@)-Lambda_("KCl")^(@)=lambda_("I")^(-)-lambda_(Cl^(-))^(@)=lambda_(I^(-))^(@)=-76.34`
or, `150.30-149.90=lambda_(I^(-))^(@)-76.34`
`therefore" "lambda_(I^(-)^(@)="76.74 ohm"^(-1)."cm"^(2)"g. equiv"^(-1)`
