The 25 pages that link to Water softening, each with the reason it gives.

• ChelationRelated: Chelating agents can bind hardness ions and reduce their interference in cleaning and processing.

• Precipitation reactionRelated: Chemical softening precipitates hardness ions as sparingly soluble compounds.

• SaltRelated: Salt regenerates ion-exchange resins used in many water softeners.

• ZeoliteBroader topic: Sodium-form zeolites can exchange sodium for hardness-causing calcium and magnesium.

• CarbonateRelated: Carbonate precipitation can remove hardness-causing ions.

• Water hardnessRelated: Softening directly reduces the mineral content measured as hardness.

• Calcium hydroxideRelated: Calcium hydroxide raises pH and precipitates magnesium and some carbonate hardness during lime softening.

• Drinking water treatmentBroader topic: Softening addresses hardness when it causes scaling or other operational problems.

• Sodium carbonateRelated: Carbonate ions precipitate hardness ions as insoluble carbonates.

• Water purificationCompared with: Softening targets hardness specifically and does not by itself make water safe to drink.

• Ion exchangeBroader topic: Sodium-form cation exchangers replace hardness ions with sodium in a standard softening process.

• Salt (chemistry)Related: Ion-exchange salts and brines are used in common softening systems.

• AluminosilicateRelated: Zeolites can soften water by exchanging sodium ions for hardness-causing ions.

• DetergentRelated: Softened water allows surfactants to clean more effectively.

• Ion-exchange chromatographyRelated: It applies cation exchange to reduce the ions responsible for hardness.

• Solubility equilibriumRelated: Precipitation equilibria can remove hardness-forming ions from water.

• Ion-exchange resinRelated: Sodium-form cation resin replaces hardness ions with sodium.

• Water chemistryRelated: It applies ion-exchange or precipitation chemistry to control hardness.

• Water disinfectionCompared with: Softening changes mineral content, not the presence or viability of pathogens.

• Mineral precipitationRelated: Precipitation methods convert dissolved hardness ions into removable solids.

• Mineral waterCompared with: Softening changes mineral content, whereas mineral water is marketed for its naturally occurring composition.

• NanofiltrationRelated: Nanofiltration can reject hardness ions while allowing much of the water to pass.

• Tectosilicate frameworkRelated: A classical use of framework cation exchange in zeolites.

• Calcium bicarbonateRelated: Treatments target calcium ions supplied by bicarbonate-bearing hard water.

• Tetrasodium EDTARelated: EDTA can bind these ions and reduce their participation in hardness-related reactions.
