The Reaction of Metals with Water. Potassium, sodium, lithium and calcium react with cold water, see alkali metals and alkaline earth metals. Metals in the reactivity series from magnesium to iron react with steam - H 2 O (g) but not water - H 2 O (l). The reaction .
Mineral Water - Lenntech
The calcium fluoride presents in nature is very different from the sodium-silica-fluoride (Na 2 SiF 6) added in drinking water, an industrial waste that is toxic and difficult to digest. People against drinking water fluorination argue that it is a violence that does not count individual choice freedom, not to mention the individual tolerance limit.
Metals in pool turn water green after adding shock, …
Calcium should be added to soft water to prevent the water from attacking and rusting metal components of the pool and filter system. This is a particular problem for areas such as the Pacific Northwest which has naturally soft water.

What Minerals are in Drinking Water – Life Ionizers
If you have hard water, it’s very easy for you to get adequate amounts of calcium and magnesium by drinking your hard water because hard water is loaded with minerals. But many people with hard water refuse to drink it, because it tastes bitter and chalky.
