The Lambda^(@) values of KNO_3 and LiNO_3 are 145.0 and 110.1S cm^(2) mol^(-1) respectively . The lambda^(@) value for K^(+) ion is 73.5 S cm^(2) mol^(-1) . Calculate lambda^(@) (Li^(+)) .

Answer»


SOLUTION :`lambda_(m)^(oo) (NO_(3)^(-)) = Lambda^(oo) (KNO_(3)) - lambda^(oo) (K^(+))`
`= 145.0 - 73.5 = 71.5 S cm^(2) mol^(-1)`
`lambda^(oo) (Li^(+)) = Lambda^(oo) (LiNO_(3)) - lambda^(oo) (NO_(3)^(-))`
`= 110.1 - 71.5 = 38.6 S cm^(2) mol^(-1)`
