QAIPMT-2010-Ch-1941: NEET 2010 Chemistry - Class 12 AIPMT-2010-Ch-1941 Solution: Which of the following expressions correctly represents the…

Which of the following expressions correctly represents the equivalent conductance at infinite dilution of

Al_2(SO_4)_3

? Given that

\Lambda^\circ_{Al^{3+}}

and

\Lambda^\circ_{SO_4^{2-}}

are the equivalent conductances at infinite dilution of the respective ions.

Multiple Choice Options

A $2\Lambda^\circ_{Al^{3+}}+3\Lambda^\circ_{SO_4^{2-}}$
B $\Lambda^\circ_{Al^{3+}}+\Lambda^\circ_{SO_4^{2-}}$
C $(\Lambda^\circ_{Al^{3+}}+\Lambda^\circ_{SO_4^{2-}})\times6$
D $\frac{1}{3}\Lambda^\circ_{Al^{3+}}+\frac{1}{2}\Lambda^\circ_{SO_4^{2-}}$

Step-by-Step Verified Solution

Equivalent conductance of an electrolyte at infinite dilution is given by the sum of equivalent conductances of the respective ions at infinite dilution.
