Demineralized water
Description
Demineralized water is water that has been freed of its ions (cations and anions), having passed through ion-exchange resins.
Uses
Demineralized water is used in the laboratory when it is important to avoid the presence of its ions: this is particularly the case when these ions need to be measured precisely in various samples.
