Calcium Chloride - an overview | ScienceDirect Topics
As previously indied, calcium salts appear to have a superior activity compared with most other metal salts, but they commonly suffer from a low solubility in water. Calcium formate acts in a manner similar to calcium chloride, but high dosages are required and its solubility is considerably less (approximately 17 g/100 g compared with 75 g/100 g at 20°C).

Standard enthalpy of formation - Wikipedia
The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard states.The standard pressure value p ⦵ = 10 5 Pa (= 100 kPa = 1 bar) is recommended by IUPAC, although prior to 1982 the value 1.00 atm (101.325 kPa) was used.
