After reading this article you will learn about:- 1. Meaning of Zeta Potential 2. Factors of Zeta Potential 3. Dispersion and Flocculation. Meaning of Zeta Potential: The potential difference (electro-osmosis and allied phenomena) between the fixed part and freely mobile portions of double layer known as Zeta potential (ζ). Mathematically it can be simplified as follows: Assuming that the diffuse [...]
After reading this article you will learn about:- 1. Concept of Diffuse Double Layer 2. Important Properties of Diffuse Double Layer 3. Factors Affecting 4. Shortcomings. Concept of Diffuse Double Layer: The exchangeable ions are surrounded by water molecules and may thus be considered as forming a solution which is often a micellar solution or inner solution. The solution containing [...]
After reading this article you will learn about:- 1. Introduction to Donnan Membrane Equilibrium 2. Assumptions of Donnan Membrane Equilibrium 3. Applications 4. Factors. Introduction to Donnan Membrane Equilibrium: If a solution of an electrolyte consisting of two diffusible ions is separated by a membrane from another solution containing a salt with a non-diffusible ion (protein ion), then at equilibrium [...]
