Calcium + Calcium Nitrate → ? | Physics Forums

2005-2-23 · The reverse does not occur significantly. One can guess that since nitric acid is known to be a strong acid, that its conjugate, being a weak base, would not react appreciably with water. I don''t believe that calcium hydroxide can be formed by simply dissolving calcium nitrate in water. And thus the point of dissolving calcium metal.

Calcium - Element information, properties and uses

Our drinking water also contains calcium ions - more so in so called hard water areas. Hard water is the term used for water with a high proportion of calcium and magnesium (2 plus) ions. The calcium usually enters the water as it flows past either calcium carbonate, from limestone and chalk, or calcium sulfate, from other mineral deposits.
