Making Lime

When water (H 2 O) is added very carefully to quicklime/burnt lime/calcium oxide (CaO), a further chemical process called hydration (also called slaking) takes place and the resulting material is called hydrated lime or slaked lime and is mainly calcium hydroxide [Ca(OH) 2]. The hydration/slaking chemical reaction is exothermic - it releases ...
