Lime is one of the most versatile chemicals in the world with numerous industrial, environmental and chemical uses. It is a white alkaline substance consisting of calcium oxide (CaO), which is obtained by heating limestone; it is also used in the production of hydrated lime [Ca(OH) 2].Due to its different geological origins and the various circumstances surrounding its …
