Question

42. For an asymmetrical strong electrolyte like Aluminum sulphate, $Al_2(SO_4)_3$, what is the mathematically strict relationship between its Molar Conductivity ($\Lambda_m$) and Equivalent Conductivity ($\Lambda_{eq}$)?

Answer: D

💡 Solution & Explanation

The relationship is defined by $\Lambda_m = \Lambda_{eq} \times z$, where $z$ is the total positive (or negative) charge per formula unit (the n-factor). For $Al_2(SO_4)_3$, the total cationic charge is $2 \times (+3) = 6$. Thus, $\Lambda_m = 6 \Lambda_{eq}$.
