Lime has been adopted because it is cheap, safe to handle and reacts readily with all types of acids from the strongest to weakest, whether organic or inorganic. The lime neutralisation process involves two steps: slaking or reaction of quicklime (calcium oxide) with water to form hydrated lime, which is a solid-liquid reaction, and reaction of hydrated lime with an acidic solution to be treated.
