Question
The molar conductivity of cation and anion of salt BA are 180 and 220 mhos respectively. The molar conductivity of salt BA at infinite dilution is_____________ .
(a) 90 mhos.cm2
(b) 110 mhos.cm2.mol-1
(c) 200 mhos.cm2.mol-1
(d) 400 mhos.cm2.mol-1
Solution
400 mhos.cm2.mol-1
Solution :-
`Delta _(BA)^@=lambda_(B^+)^@+lambda_(A^-)^@`
= 180 + 220
= 400 mhos cm2 mol−1
