The molar conducatance of `Ba^(2+)` and `Cl^(-)` are `127` and `76 ohm^(-1) cm^(-1) mol^(-1)` respectively at infinite dilution. The equivalent conductance of `BaCl_(2)` at infinte dilution will beA. 139.52B. 203C. 279D. 101.5

Answer» Correct Answer - A
(a)The equivalent conductance of `BaCl_(2)` at infinite dilution.
`lambda_(oo) " of " BaCl_(2)=(1)/(2) lambda_(oo) " of " Ba^(2+) + lambda_(oo) " of " Cl^(-)`
`=(127)/(2)+76=139.5`
