Cao, Y.; Li, W.Y.; Pan, … 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 $\ce{SO2}$). 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. au シュミレーション 機種変更
