CaO (s) + H2O (l) --> Ca(OH)2 (s)
CaO is commonly called lime or quicklime. When you add water to it you get Ca(OH)2 which is commonly called slaked lime, or hydrated lime.

Calcium hydroxide is a chemical compound with the chemical formula Ca(OH)2. It is a colourless crystal or white powder, and is created when calcium oxide (called lime or quicklime) is slaked with water. It can also be created by mixing an aqueous solution of calcium chloride and an aqueous solution of sodium hydroxide. A traditional name for calcium hydroxide is slaked lime, or hydrated lime.
If heated, calcium hydroxide decomposes into calcium oxide and water. A suspension of fine calcium hydroxide particles in water, called lime water (or milk of lime), is a medium strength base that reacts violently with acids and attacks many metals in presence of water.
