What is the relationship between equivalent conductance and molar conductance ? Illustrate by taking the example of `Al_(2)(SO_(4))_(3)`.

Text Solution

AI Generated Solution

To understand the relationship between equivalent conductance and molar conductance, we will first define both terms and then illustrate the relationship using the example of \( \text{Al}_2(\text{SO}_4)_3 \). ### Step 1: Definitions 1. **Equivalent Conductance (\( \Lambda_{\text{eq}} \))**: This is the conductance of an electrolyte solution when 1 gram equivalent of the electrolyte is dissolved in a given volume of solution. It is expressed in units of S cm²/equiv. 2. **Molar Conductance (\( \Lambda_{\text{m}} \))**: This is the conductance of an electrolyte solution when 1 mole of the electrolyte is dissolved in a given volume of solution. It is expressed in units of S cm²/mol. ### Step 2: Formulas ...
