What is the effect of decreasing concentration on the molar conductivity of a weak electrolyte?

Text Solution

AI Generated Solution

To understand the effect of decreasing concentration on the molar conductivity of a weak electrolyte, let's break down the solution step by step: ### Step 1: Define Molar Conductivity Molar conductivity (Λm) is defined as the conductivity (κ) of an electrolyte solution divided by its molar concentration (C). It is expressed as: \[ \Lambda_m = \frac{\kappa}{C} \] ### Step 2: Understand Weak Electrolytes Weak electrolytes are substances that partially ionize in solution. This means that not all of the solute molecules dissociate into ions when dissolved in water. ...
