WebCa (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 hydrogen gas. Other important calcium reaction mechanisms are erosion reactions. These usually occur when carbon dioxide is present. Under normal conditions calcium carbonate is water insoluble. WebTherefore cooling systems are plagued with corrosion. Many factors affect corrosion rates in a given cooling water system. The presence of dissolved gases, chloride and sulfate levels, pH, alkalinity, scaling tendency, and protective ions such as calcium, magnesium, phosphate nitrate, and silicate must all be taken into consideration.
