Calcium hydroxide | Sciencemadness Wiki | FANDOM powered

Calcium hydroxide, also known by the names slaked lime and hydrated lime, is an inorganic compound with chemical formula Ca(OH) 2.It serves as an intermediate amongst basic calcium compounds, as it can be converted to both calcium oxide or calcium carbonate with relative ease. It is a great starting point for other calcium compounds.

Calcium - Wikipedia

Calcium is a chemical element with the syol Ca and atomic nuer 20.
