Calcium hydroxide is also known as lime or sometimes slaked lime Because of the amount of heat given out in this reaction sometimes the bodies of people who had died of disease particularly bubonic plague were covered in quicklime before they were buried it was thought that the high temperatures reached as the lime became damp would destroy whatever it was that was causing the diseaseThe brittle gray calcium carbide formed from mixing coal tar and lime released acetylene gas when placed in water Confident that acetylene would achieve wide use in city lighting and heating eight companies purchased the rights to manufacture calcium carbide
