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

Options

A. `2lambda_(Al^(3+))^(@)+3lambda_(SO_(4)^(2-))^(@)`
B. `lambda_(Al^(3+))^(@)+lambda_(SO_(4)^(2-))^(@)`
C. `lambda_(Al_(3)^(3+))^(@)+lambda_(SO_(4)^(2-))^(@)`
D. `(1)/(3)lambda_(Al^(3+))^(@)+(1)/(2)lambda_(SO_(4)^(2-))^(@)`

Answer

B

Explanation

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