The model is in this report applied on the absorption of a flue gas into a NaOH scrubber solution. Thermodynamic properties of substances The solubility of the substances Periodic table of elements. Sulfur dioxide react with sodium hydroxide. Sodium hydroxide - concentrated solution. At higher concentrations (29-290 mg/cu m, 10-100 ppm), the fraction absorbed is much higher (about 95%). Simultaneous Sulfur Dioxide Absorption and Hydrogen Sulfide Generation in an Aqueous Solution of Sodium Sulfide. Sulfur dioxide (SO2) and sodium hydroxide (NaOH) react to form sodium sulfite (Na2SO3) and water (H2O) by the following reaction. 26. Find another reaction. Our channel. Sodium hydroxide also reacts with acidic oxides, such as sulfur dioxide. Sulfur dioxide gas reacts with sodium hydroxide to form sodium sulfite and water. The unbalanced chemical equation for this reaction is given below: SO 2 ( g ) + NaOH ( s ) → Na 2 SO 3 ( s ) + H 2 O ( l ) Assuming you react 38.3 g sulfur dioxide with 32.8 g sodium hydroxide and assuming that the reaction goes to completion, calculate the mass of each product formed. here includes sodium hydroxide and sodium salts that makes it possible to study simultaneous absorption of flue gas components in alkaline scrubber solutions. Environmental Science & Technology 1996 , 30 (2) , 377-384. The absorption of sulfur dioxide into highly concentrated sodium hydroxide in a spray column from simulated flue gas was investigated. Sulfur dioxide is highly soluble in aqueous media. The influences of different operating conditions on the SO 2 removal efficiency, such as sodium hydroxide concentration, liquid-to-gas ratio, gas velocity and SO 2 concentration, were examined. 25. SO 2 + 2NaOH → Na 2 SO 3 + H 2 O [ Check the balance ] Sulfur dioxide react with sodium hydroxide to produce sodium sulfite and water. 27. The process defined in claim 24 wherein said alkaline solution is an aqueous solution of ammonium hydroxide. In rabbits, about 40% of the inhaled sulfur dioxide is absorbed in the nose and pharynx when concentrations of about 290 ug/cu m (0.1 ppm) are inhaled. For example, + + Reaction with metals and oxides. The process defined in claim 24 wherein said alkaline solution is an aqueous solution of sodium hydroxide. A process for removing sulfur dioxide from a gaseous mixture comprising: Such reactions are often used to "scrub" harmful acidic gases (like SO 2 and H 2 S) produced in the burning of coal and thus prevent their release into the atmosphere.
