Calcium hydroxide (Ca(OH) 2), known as slaked lime, is a colorless crystal or white powder. It is produced when calcium oxide is "slaked" (hydrated) with water. It can also be made by mixing aqueous solutions of calcium chloride and sodium hydroxide. If heated, calcium hydroxide decomposes into calcium oxide and water.
