Jun 05, 2020 · During a process called calcination, calcium carbonate (limestone) is burned and decomposes into calcium oxide (pure lime). When the calcium oxide, a white powder, is mixed with water, it becomes calcium hydroxide (Ca(OH) 2)­. Calcium hydroxide is the lime that scientists talk about when they talk about adding lime to our oceans.

Calcium carbonate is an exceptional compound. The chemical formula CaCO 3 represents a raw material that exists everywhere in nature – whether dissolved in rivers and oceans, melted as "cold" carbonatite lava and solidified as a mineral, dripstone or as a parent material for whole mountain ranges..

Calcium carbonate is an inorganic chemical compound with the chemical formula CaCO3. Calcium carbonate is one of the most popular chemicals which is first encountered in school classrooms, where the use of chalk (a form of CaCO3) is found. It is found in the earthâ??s crust. It is also found in many forms such as marble, limestone, etc.

Limestone is a naturally occurring mineral high in calcium carbonate, or CaCO3. It's possible to extract pure calcium from calcium carbonate through a multistage process requiring special equipment. Pure calcium reacts very quickly with the oxygen in the air, so you must store it in a nonreactive atmosphere, such as in a vacuum container.

Lime water turns milky in the presence of carbon dioxide due to formation of calcium carbonate: Ca(OH)2 + CO2 → CaCO3 + H2O. Calcium hydroxide is produced commercially by treating lime with water: CaO + H2O → Ca(OH)2. The tricky point in manufacturing process is the selection of good quality limestone for making lime CaO.
