Hardness - Water Quality Association

Hard water is a common quality of water which contains dissolved compounds of calcium and magnesium and, sometimes, other divalent and trivalent metallic elements. Dissolved calcium and magnesium salts are primarily responsible for most scaling in pipes and water heaters and cause numerous problems in laundry, kitchen, and bath.

Advanced Water Treatment Concepts

As with all other chemicals used in water treatment there are benefits and drawbacks to its use. The benefits of calcium hypochlorite are that it is more stable than the liquid form and it has a longer shelf life. The primary drawback in using solid chlorine is that it must be mixed with water before it can be added to the water system.

Calcium (Ca) and water - Lenntech

In what way and in what form does calcium react with water? Contrary to magnesium placed directly above calcium in the periodic chart, elementary calcium reacts with water at room temperature, according to the following reaction mechanism: Ca (s) + 2H 2 O (g) -> Ca(OH) 2 (aq) + H 2 (g) This reaction forms calcium hydroxide that dissolves in water as a soda, and …
