Working with Lime
Heat acting upon calcium carbonate (CaC(3) produces calcium oxide (CaO) plus carbon dioxide (CO2). The chemical reaction is usually ... calcium hydroxide, which is the first step to reversing the process back to calcium carbonate. Just as making quicklime needed heat, the reverse process produces heat: calcium oxide (CaO) plus water (H2) produces calcium ...

Calcium (Ca)
Calcium werd voor het eerst gesoleerd door Sir Humphry Davy in 1808 door de elektrolyse van een mengsel van kalk (CaO) en kwik oxide (HgO). Momenteel wordt calcium gewonnen door calcium ionen in kalk uit te wisselen met aluminium ionen in ionenwisselaars. Ongeveer 4,2% van de aardkorst bestaat uit calcium. Door de ...
