Question

Which of the following expressions correctly represents the equivalent conductance at infinite dilution of Al2(SO4)3 ? Given that ∧°Al3+ and - ∧°SO2-4 are the equivalent conductances at infinite dilution of the respective ions (A)  ∧°Al3+ + ∧°SO42- (B)  (∧°Al3+ + ∧°SO42- ) × 6 (C)  (1/3)∧°Al3+ + (1/2) ∧°SO42-  (D) 2 ∧°Al3+ + 3 ∧°SO42-

Al2(SO4)32Al3++3SO42-. Since equivalent conductance's are given only for ions, the equivalent conductance at infinite dilution, Lambda eq∞ = Lambda Al 3+o+ Lambda so42-o

Q. Which of the following expressions correctly represents the equivalent conductance at infinite dilution of $A l_{2} (S O_{4})_{3}$ ? Given that $\land_{A l^{3 +}}^{\circ}$ and $- \land_{S O_{4}^{2 -}}^{\circ}$ are the equivalent conductances at infinite dilution of the respective ions

$\land_{A l^{3 +}}^{\circ} + \land_{S O_{4}^{2 -}}^{\circ}$

$(\land_{A l^{3 +}}^{\circ} + \land_{S O_{4}^{2 -}}^{\circ}) \times 6$

$\frac{1}{3} \land_{A l^{3 +}}^{\circ} + \frac{1}{2} \land_{S O_{4}^{2 -}}^{\circ}$

$2 \land_{A l^{3 +}}^{\circ} + 3 \land_{S O_{4}^{2 -}}^{\circ}$

$A l_{2} (S O_{4})_{3} 2 A l^{3 +} + 3 S O_{4}^{2 -}$ .
Since equivalent conductance's are given only for ions, the equivalent conductance at infinite dilution,
$Λ_{e q}^{\infty} = Λ_{A l 3 +}^{o} + Λ_{s o_{4}^{2 -}}^{o}$
