Elementary calcium reacts with water. Calcium compounds are more or less water soluble. Calcium carbonate has a solubility of 14 mg/L, which is multiplied by a factor five in presence of carbon dioxide. Calcium phosphate solubility is 20 mg/L, and that of calcium fluoride is 16 mg/L. Cal...
27 Calcium reacts with water to form calcium hydroxide and hydrogen.Ca(S)+2H_2O(l)→Ca(OH)_2(S)+H_2(g) The standard enthalpy change for this reaction can be determined experimentally.What further information are needed to calculate the standard enthalpy change of formation of calcium hydro...

CaH2 was found to be ineffective as a drying agent, and upon heating the electrolyte tetrafluoroborate anion was found to react with water producing CaF2 and lowering the salt concentration of the electrolyte. 11B qNMR was implemented as a useful and simple method to evaluate the final salt ...
The commercially produced metal reacts easily with water and acids and it produces hydrogen which contains remarkable amounts of ammonia and hydrocarbides as impurities. Applications The metal is used in aluminium alloys for bearings, as a helper in the bismuth removal form lead, as well as in ...
