A process where positively charged ions of one chemical are preferentially replaced by positive ions of another chemical. For example, water softeners replace Ca+2, and Mg+2 ions with the sodium (Na+2) ion.
The ability of clay and humus to attract and exchange positive ions.
The exchange of cations held by the soil adsorbing complex with other cations. Thus, if a soil adsorbing complex is rich in sodium, treatment with calcium sulphate (gypsum) causes some calcium cations to exchange with some sodium cations.
Cation Exchange - Process where positively charged ions of one chemical are preferentially replaced by positive ions of another chemical.
Ion exchange process in which cations in solution are exchanged for other cations form and ion exchanger.
The ion exchange that happens in the resin, whereby your resin is regenerated.
A process in which positively charged minerals are made available to a plant when hydrogen ions in the soil displace mineral ions from the clay particles.
A process in which cations in solution are exchanged with cations held on the exchange sites of mineral and organic matter, particularly on the surfaces of colloids of clay and humus.
The clay and organic matter of soil have a net negative charge. As a result of these charges, positively charged ions (cations) such as hydronium H3O+, potassium K+, ammonium NH4+, calcium Ca2+, magnesium Mg2+, aluminum Al3+, may be held at the surface of the clay or organic particles and exchanged with other ions in the solution or with ions at the plant root's surface.
replacement by a cation in solution for an absorbed cation of negatively charged sites of a solid. Cation exchange capacity (CEC) - the sum total of exchangeable cations that a soil can absorb, expressed in centimolesc per kg of soil or colloid.
The interchange between a cation in solution and another cation on the surface of any surface-active material, such as clay colloid organic colloid, or plant root surface.
Chemical trading of cations between the soil minerals and organic matter with the soil solution and plant roots.
The ion exchange process in which cations in solution are exchanged for other cations available from an ion exchange product. Formerly called base exchange.
