Soda lime is a mixture of sodium hydroxide and calcium oxide used to eliminate carbon dioxide from breathing gases in anesthesia, submarines, rebreathers, and hyperbaric chambers. Learn about its chemical composition, reaction, applications, and analogy with the alkali–silica reaction in concrete.
Chemical Formula of Calcium Oxide is CaO. Question 2: How Calcium oxide is prepared? Answer: Calcium oxide is prepared by the process called calcination which involves heating the calcium carbonate (CaCO 3) at high temperature, causing it to decompose and release carbon dioxide (CO2), leaving behind calcium oxide (CaO). CaCO 3 (g)→CaO(s) + CO(g)
Calcium oxide (CaO) is a white, caustic, alkaline, crystalline solid that is widely used as quicklime or burnt lime. It is made by heating calcium carbonate (CaCO3) to above 825 °C in a lime kiln.
