Increasing CO 2 also makes the water more acidic and decreases the pH. The calcium carbonate scaling usually occurs with a pressure drop, for example, at the wellbore. This reduces the partial pressure of CO 2, thereby increasing the pH and decreasing the CaCO 3 solubility. The solubility of calcium carbonate decreases with increasing temperature.

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.
