Understand Kohlrausch's law and its applications for calculating degree of dissociation and dissociation constant of weak electrolytes. This document provides a comprehensive revision guide for Class 12 Chemistry, focusing on key concepts in Physical Chemistry. Question 3: What is molar elevation constant? Does it depend on nature of solute? Molar Elevation Constant (Kb) The molar elevation constant, also called the ebullioscopic constant (K b), is defined as the elevation in boiling point produced when one mole of a non-volatile solute is dissolved in one kilogram of solvent. Molar conductivity is the conductance of a volume of solution containing 1 mole of dissolved electrolyte when placed between two parallel electrodes 1 cm apart and large enough to contain between them all the solution. As we can observe from the graph, weak electrolytes have lower molar conductivities and lower degree of dissociation at higher concentrations which increases steeply at lower concentrations. The electrolyte X is: 1. 9 S cm² mol⁻¹ respectively, and the molar conductivity of a 1 × 10⁻² M solution of NH4OH as 9.
