Calcium Hydroxide Encyclopedia

OverviewHow It Is MadeCommon Uses and Potential HazardsInteresting FactsFor Further InformationCalcium hydroxide (KAL-see-um hye-DROK-side) is a soft, white odorless solid that occurs as granules or a powder. It has a slightly bitter, alkaline taste. Calcium hydroxide absorbs carbon dioxide readily from the air, changing to calcium carbonate (CaCO3). For this reason, the compound often is contaminated with the carbonate unless it is kept in tightly sealed containers. Calcium hydroxide is a relatively inexpensive chemical and, for that reason, is used in productio
