The values of `Lambda_(m)^(@)` for the aqueous solution of KCl and `KNO_(3)` are `149.86ohm^(-1)"cm"^(2)mol^(-1) and 145 ohm^(-1)cm^(2)mol^(-1)`, respectively. If `lambda_(m)^(@)(Cl^(-))` is `"76.44 ohm"^(-1)."cm"^(2)."mol"^(-1)` then `lambda_(m)^(@)(NO_3^(-))`will be?

Text Solution

Verified by Experts

`Lambda_(m)^(@)(KCl)-Lambda_(m)^(@)(KNO_(3))=lambda_(m)^(@)(Cl^(-))-lambda_(m)^(@)(NO_(3)^(-))`
`149.86-145=76.44-lambda_(m)^(@)(NO_(3)^(-))`
`therefore" "lambda_(m)^(@)(NO_(3)^(-))="71.58 ohm"^(-1)."cm"^(2)."mol"^(-1)`
