Reaction between cao and so2
WebA reaction is also considered to be a decomposition reaction even when one or more of the products is still a compound. A metal carbonate decomposes into a metal oxide and carbon dioxide gas. For example, calcium carbonate decomposes into calcium oxide and carbon dioxide. CaCO 3(s) → CaO(s) + CO 2(g) WebCaCO3(s) + SO2(g) → CaSO3(s) + CO2(g) When wet scrubbing with a Ca (OH)2 ( hydrated lime) slurry, the reaction also produces CaSO3 ( calcium sulfite) and may be expressed in the simplified dry form as: Ca (OH)2(s) + …

WebAug 1, 2024 · So, the reaction between $\ce{CaO}$ and $\ce{SO2}$ can be considered an acid-base reaction. There is a somewhat obscure acid-base theory, the Lux–Flood theory, which is applicable to such reactions. In this context, bases are oxide donors (like $\ce{CaO}$) and acids are oxide acceptors (like $\ce{SO2}$). WebCaO (s) + H2O (l) → Ca (OH) 2 (s) This reaction occurs when water is added to dry portland cement to make concrete, and heat evolution of energy as heat is evident because the mixture becomes warm. Not all reactions are …
WebThe synergistic effect between SO 2 and NO 2 was not observed on other mineral particles (such as CaCO 3 and CaSO 4) probably due to the lack of the surface reactive oxygen sites. The synergistic reaction between SO 2 and NO 2 on mineral oxides resulted in the formation of internal mixtures of sulfate, nitrate, and mineral oxides. WebThe reactions occurring between CaCO3/CaO and SO2/SO3 in oxidizing atmospheres are discussed. Calcination and sulphation were carried out in a thermobalance under …
