After reading this article you will learn about:- 1. Definition of Ion-Exchange 2. Site for Ion Exchange 3. Kinds of Exchangeable Ions 4. Factors Affecting Ion-Exchange. Definition of Ion-Exchange: Ion-exchange is defined as a reversible process by which cations and anions are exchanged between solid and liquid phases, and between solid phases it in close contact with each other. For [...]
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 of soil; C = ion [...]
After reading this article you will learn about the relationship between percentage base saturation of soil and its ph. The determination of soil pH is comparatively more easier than that of determining base saturation. If pH is determined the base saturation can then be estimated approximately. A low percentage base saturation means acidity, whereas a percentage base saturation approaching 100 [...]
