The electrolyte `A_(2)B` dissociates in aqueous solution as `A_(2)B(aq)rarr 2A^(+)(aq)+B^(2-)(aq)`. If molar ionic conductance at infinite dilution of `A^(+) and B^(2-)` ions are `lambda_(m)^(@)(A^(+)) and lambda_(m)^(@)(B^(2-))` respectively when what will be the value of `Lambda_(m)^(@)` of `A_(2)B` ?

Text Solution

Verified by Experts

`Lambda_(m)^(@)=2lambda_(m)^(@)(A^(+))+lambda_(m)^(@)(B^(2-))`
