calcium | Definition, Properties, & Compounds | …

Calcium hypochlorite, Ca(ClO 2), widely used as bleaching powder, is produced by the action of chlorine on calcium hydroxide. The hydride CaH 2, formed by the direct action of the elements, liberates hydrogen when treated with water. Traces of water can be removed from many organic solvents by refluxing them in the presence of CaH 2.
