Classification of Ion-Exchange Equations: 3 Groups | Soil Colloids
Article shared by :
This article throws light upon the three groups of ion-exchange equations. The groups are: 1. Empirical Formula 2. Kinetic or Statistical Formula 3. Mass Action. 1. Empirical Formula: The Freundlich equation is one of the first used in soil studies and it states that, m = ACB where, m = amount adsorbed per unit weight […]
