Substance that will remove sulfur dioxide?
Basically, sulfur dioxide is a acidic gas. As acid reacts with alkali, carbonates and metals, all 3 are actually ideal to remove sulfur dioxide. However, in the context of removing sulfur dioxide due to air pollution, reacting sulfur dioxide with alkali and carbonate would be more appropriate. For example, removing sulfur dioxide with calcium carbonate would result in calcium sulfate, water and carbon dioxide.
How can sulfur dioxide be removed using calcium oxide?
Sulfur dioxide can be removed by scrubbing the gas with a solution of calcium oxide. The calcium oxide reacts with sulfur dioxide to form calcium sulfite, which can then be further oxidized to calcium sulfate. This process helps to reduce the concentration of sulfur dioxide in the gas stream.
What substance can be used to get rid of sulphur dioxide?
Substances like activated carbon, hydrogen peroxide, or sodium hydroxide can be used to remove sulfur dioxide. These substances react with sulfur dioxide to form less harmful compounds or to neutralize its effects.
What type of solution is used to remove sulfur dioxide?
One common solution to remove sulfur dioxide is to use a wet scrubber system. This technology involves spraying a solution (such as a lime or limestone slurry) onto the flue gas containing sulfur dioxide to neutralize and remove it. The sulfur dioxide reacts with the solution to form a solid byproduct that can be easily separated.
How does limestone remove sulphur dioxide?
The lime (CaO) reacts with SO2: 2CaO (s) + 2SO2 (g) + O2(g) .........> 2 CaSO4 (s) So the sulphur dioxide is removed and deposited as calcium sulphate.
Which chemical could be used to remove the acidic sulphur dioxide from flue gases?
Lime (calcium oxide or calcium hydroxide) is commonly used to remove acidic sulfur dioxide from flue gases. The sulfur dioxide reacts with lime to form calcium sulfite or calcium sulfate, which can then be removed from the gas stream.

For example, removing sulfur dioxide with calcium carbonate would result in calcium sulfate, water and carbon dioxide.
What kind of reaction occurs when sulphur dioxide reacts with lime water?
When sulfur dioxide reacts with lime water (calcium hydroxide), calcium sulfite is formed. This reaction involves the neutralization of sulfur dioxide, leading to the formation of a white precipitate of calcium sulfite. This reaction is the basis for using lime water as a method to detect the presence of sulfur dioxide gas.
What substance is added in the final stages to remove the sulfur from coal?
Limestone is typically added in the final stages to remove sulfur from coal during a process called flue-gas desulfurization. Limestone reacts with sulfur dioxide to form calcium sulfate, which can then be easily removed.
How can sulfur dioxide be removed using calcium oxide?
Sulfur dioxide can be removed by scrubbing the gas with a solution of calcium oxide. The calcium oxide reacts with sulfur dioxide to form calcium sulfite, which can then be further oxidized to calcium sulfate. This process helps to reduce the concentration of sulfur dioxide in the gas stream.
Sulfur dioxide is released in the combustion of coal Scrubbers use lime slurries of calcium hydroxide to remove the SO2 from flue gases Write a balanced equation for this reaction?
SO2 + Ca(OH)2 = CaSO3 + H2O The products are Water and Calcium Sulphite ; Note the spelling of the sulphur anion; NOT sulphate.
Sulfur dioxide gas is passed over solid calcium oxide?
When sulfur dioxide gas is passed over solid calcium oxide, a chemical reaction occurs to produce solid calcium sulfite. The reaction can be represented by the equation: SO2(g) + CaO(s) -> CaSO3(s). This reaction is used in industries to remove sulfur dioxide from gas emissions.
What happens when sulfur dioxide reacts with calcium hydroxide?
Ca(OH)2 + H2SO4 --> CaSO4 + 2H2O Acid base neutralization reaction producing a salt and water.
How is sulfur removed in power stations?
Sulfur can be removed from emissions at power stations through a process called flue gas desulfurization, which involves injecting a substance like limestone or lime into the exhaust gases. This reacts with the sulfur dioxide to form compounds like calcium sulfite or sulfate, which are then removed from the gases before being released into the atmosphere. Another method is called dry sorbent injection, where a powdered sorbent such as calcium hydroxide is injected into the flue gas to react with sulfur dioxide.
What substance can be used to get rid of sulphur dioxide?
Substances like activated carbon, hydrogen peroxide, or sodium hydroxide can be used to remove sulfur dioxide. These substances react with sulfur dioxide to form less harmful compounds or to neutralize its effects.
How do you get rid of sulfur Dioxide?
Sulfur dioxide can be removed by various methods including adsorption, chemical reaction, and scrubbing. Common techniques include using activated carbon, oxidation with hydrogen peroxide, and scrubbing with alkaline solutions like sodium hydroxide or calcium hydroxide. Choose a method based on the specific source of sulfur dioxide emissions and the desired level of removal.
Why sulfur dioxide turns lime water milky?
This is the same principle as to carbon dioxide:Calcium sulfite is insoluble, thus precipitating, in saturated Ca(OH)2 solution.Ca2+ + 2 OH- + SO2,gas --> CaSO3,precip. + H2OCompare:Ca2+ + 2 OH- + CO2,gas --> CaCO3,precip. + H2O
