Calcium chloride - Wikipedia

2019-4-24 · Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white coloured crystalline solid at room temperature, highly soluble in water. Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl2(H2O)x, where x = 0, 1, 2, 4, and 6. These compounds are mainly used for de-icing and

Alkaline-earth Metals | Encyclopedia

2019-4-25 · Yet another similarity the alkaline earth metals have with the alkali metals is the fact that four of the them — magnesium, calcium, strontium, and barium — were either identified or isolated in the first decade of the nineteenth century by English chemist Sir Humphry Davy (1778-1829). Around the same time, Davy also isolated sodium and potassium from the alkali metal family.
