Web19 okt. 2024 · The ion exchange process will take place between a liquid and a solid. While the liquid is always water, the solid can be either zeolite or a resin material. Keep in mind that resin materials can only be charged for a specific period of time. When ions are no longer able to be exchanged, the resin will need to be recharged. WebIon exchange resins, in the form of beads, are a functional component of domestic water softening units. Conventional water-softening appliances intended for household use depend on an ion-exchange resin in which "hardness ions"—mainly Ca 2+ and Mg 2+ —are exchanged for sodium ions.

An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange.
