Which of the following expressions correctly represents the equivalent conductance at infinite dilution of `Al_(SO_(4_(3))`. Given that `overset(@)Lambda_(Al^(3+))` and `overset(@)Lambda_(SO_(4)^(2-))` are the equivalent conduactance at infinite dilution of the respective ions?

Options

A. `2overset(@)Lambda_(Al^(3+))+3overset(@)Lambda_(SO_(4)^(2-))`
B. `overset(@)Lambda_(Al^(3+))+overset(@)Lambda_(SO_(4)^(2-))`
C. `6(overset(@)Lambda_(Al^(3+))+overset(@)Lambda_(SO_(4)^(2-)))`
D. `(1)/(3)overset(@)Lambda_(Al^(3+))+(1)/(3)overset(@)Lambda_(SO_(4)^(2-))`

Answer

B

Explanation

At infinite dilution, when dissociation is complete, each ion makes a definite contribution toward molar conductance of the electrolyte toward molar condutance of the electrolyte irrespective of the nature of the other ion with which it is associated.
