WebResultant carbon dioxide passed through limewater in the right tube, producing a milky solution due to precipitation of the insoluble suspension of calcium carbonate : Ca (OH) 2(aq) + CO 2(g) → CaCO 3(s) + H 2 O (l) If excess CO 2 is added: the following reaction takes place: CaCO 3(s) + H 2 O (l) + CO 2(g) → Ca (HCO 3) 2(aq) WebApr 12, 2003 · Hydrochloride (HCl) is an acidic pollutant present in the flue gas of most municipal or hazardous waste incinerators. Hydrated lime (Ca(OH)2) is often used as a dry sorbent for injection in a spray reactor to remove HCl. However, due to the short residence time encountered, this control method has generally been found to have low conversion …
