Question

Calculate \( \lambda_{m} \) for \( C l^{-} \)ion from the data ginen below: \[ \begin{array}{l} \lambda_{m}^{0} MgCl _{2}=258.6 sm ^{2} \text { mol-1 and } \lambda_{m} Mg ^{2+} \\ =106 scm ^{2} mol ^{-1} \\ \end{array} \] \[ \rightarrow N \cdot 8 \]

Answer 1

∧⁰m (MgCl₂) = λ⁰m (Mg²⁺) + 2 λ⁰m (Cl-)

258.6 = 106 + 2 λ⁰m (Cl-)

λ⁰m (Cl-) = 76.3 Scm² mol^-1
