What is the difference between softened water and deionized water? bbs.hcbbs.com/archiver/tid-398301.html
Softened water refers to water whose hardness (mainly referring to calcium and magnesium ions in the water) has been removed or reduced to a certain extent. During the softening process of water, only its hardness decreases, while the total amount remains unchanged. Deionized water: As the name suggests, it is water from which all ions resulting from the dissociation of electrolytes in water have been removed, with the exception of hydrogen ions and hydroxide ions. That is, to remove the electrolyte substances dissolved in water. Since the ions produced by the ionization of electrolytes in water increase the water’s conductivity, the purity of deionized water is naturally measured by its conductivity. Deionized water is basically produced by ion exchange. However, deionized water can contain non-electrolytes that cannot be ionized, such as ethanol.
Softened water merely reduces the hardness of water, while deionized water requires even higher standards.
