The reaction of quicklime with water produces calcium hydroxide with the chemical equation: CaO + H2O → Ca(OH)2.
This reaction is an exothermic reaction, meaning that a large amount of heat is released during the reaction, enough for the water to boil in the reaction. Therefore, care needs to be taken when handling quicklime to avoid burns due to reaction exothermic heat !
Lime in contact with water will produce a sharp chemical reaction, instantly release a lot of heat, but if in a larger space is not an explosion, but if the amount of lime in a plastic bottle is relatively large, the heat generated by the chemical reaction will make the plastic bottle expand rapidly, seriously will make the plastic bottle burst !
Calcium hydroxide is a strong alkali, with bactericidal and antiseptic ability, on the skin, fabric corrosion. Calcium hydroxide is used in the manufacture of bleaching powder, hard water softener, disinfection insecticide, hair removal agent for leather, sugar refining and building materials !
