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. `2lamda_(Al^(3+))^(@)+3lamda_(SO_(4)^(2-))^(@)`
B. `lamda_(Al^(3+))^(@)+lamda_(SO_(4)^(2-))^(@)`
C. `lamda_(Al^(3+))^(@)+lamda_(SO_(4)^(2))^(@)xx6`
D. `(1)/(3)lamda_(Al^(3+))^(@)+(1)/(2)lamda_(SO_(4)^(2-))`

Answer

B

Explanation

`wedge_(eq)^(@)[Al_(2)(SO_(4))_(3)]=lada_(Al^(3+))^(@)+lamda_(SO_(4)^(2-))^(@)`
