Why `Lambda_(m)^(@)" for "CH_(3)COOH` cannot be determined experimentally ?

Text Solution

AI Generated Solution

To understand why the molar conductance at infinite dilution (λm^∞) for acetic acid (CH₃COOH) cannot be determined experimentally, we can break down the explanation into several steps: ### Step-by-Step Solution: 1. **Definition of Molar Conductance**: Molar conductance (λ) is defined as the conductance of an electrolyte solution divided by its molar concentration. It is a measure of how well ions in a solution can conduct electricity. 2. **Infinite Dilution Concept**: ...
