Ca(OH)2 - CALCIUM HYDROXIDE. Properties of calcium hydroxide: Hydrated lime, Portland. White, decomposes on heating without melting. Poorly soluble in water (is formed diluted alkaline solution).

Calcium hydroxide is formed by the action of water on calcium oxide, also called slaked lime, Ca(OH)2. A small proportion of it dissolves when combined with water, forming a solution known as limewater, the remainder remaining in a suspension called lime

How do you make calcium hydroxide (Ca(OH)2) from Calcium carbonate (CaCO3) and what are the equations. Thermally decompose the calcium carbonate:CaCO 3 -> CaO + CO 2 Now mix the CaO with water:CaO + H 2 O -> Ca(OH) 2
