What is the formula of the acid formed when SO2 reacts with water?

Therefore when the sulphur is burned in presence of oxygen it produces sulphur dioxide and some trace amount of sulphur trioxide whose chemical formula is SO3 . Therefore sulphurous acid (H2SO3) is formed when sulphur dioxide dissolves in water.

What human activity releases sulfur dioxide into the air?

These gases especially SO2 are emitted by the burning of fossil fuels — coal oil and diesel — or other materials that contain sulfur. Sources include power plants metals processing and smelting facilities and vehicles.

How is Sulphur dioxide an air pollutant?

How SO2 is air pollutant? Sulphur dioxide (SO2) is an air pollutant made up of sulphur and oxygen atoms and is harmful to both plants and people. On dissolution in rain water SO2 produces acid rain. This SO3 gets converted into H2SO4 in the presence of moisture which comes down in the form acid rain.

How is sulfur dioxide removed from the air?

It is possible to scrub sulfur dioxide by using a cold solution of sodium sulfite this forms a sodium hydrogen sulfite solution. By heating this solution it is possible to reverse the reaction to form sulfur dioxide and the sodium sulfite solution.

When Sulphur is dissolved in water then?

Answer : When sulphur dioxide is dissolved in water then it forms sulphurous acid (H2SO3). Explanation: Metals react with oxygen to form metallic oxides. These metallic oxides are basic in nature because they react with water to form bases.

Is Sulphur dioxide being released in the air a chemical change?

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.

What happens when sulphur dioxide SO2 react with water H2O?

The reaction of Sulphur dioxide with water leads to the formation of acid called Sulfurous acid. … When the gas is dissolved in water it yields an acid called sulfurous acid with chemical formula as shown in the chemical equation: Sulfurous acid is a good reducing agent with molar mass 82.07g/mol.

What is observed when sulphur dioxide is passed through water and lime water class 10?

-When sulfur dioxide is passed through lime water a white precipitate of calcium sulfite (CaSO3)is formed which further reacts with sulfur dioxide in excess to form calcium hydrogen sulfite.

When sulphur reacts with oxygen the oxide formed is?

When sulphur reacts with oxygen the oxide formed is Acidic or Alkaline in nature. The oxide formed is Sulphur dioxide .

What happens when sulphur dioxide is dissolved in water write chemical equation for the reaction which takes place?

SO2 + H2O ——––> H2SO3.

When sulfur dioxide SO2 reacts with water vapor in the atmosphere it produces?

When sulfur dioxide (SO2) reacts with water vapor in the atmosphere it produces: sulfuric acid (H2SO4). Burning fossil fuels releases among others two gases primarily responsible for acid rain.

When sulphur dioxide is dissolved in water a sulphur is formed B sulphur trioxide is formed C Sulphuric acid is formed d sulphurous acid is formed?

The correct answer is Sulfurous acid. Sulfurous acid is a good reducing agent. Sulfurous acid is a colourless liquid.

How do humans release sulfur into the atmosphere?

Sulfur an essential element for the macromolecules of living things is released into the atmosphere by the burning of fossil fuels such as coal. … Sulfur can also fall directly from the atmosphere in a process called fallout. Also the weathering of sulfur-containing rocks releases sulfur into the soil.

How do humans add sulfur dioxide to the air?

The primary anthropogenic source of sulfur dioxide gas is fuel combustion from power generation and industrial processes. … Sulfur dioxide emission from fuel combustion have come primarily from coal burning with coal combustion producing 96% of the electric utility emissions.

How does sulfur dioxide move through the environment?

Sulphur dioxide reacts on the surface of a variety of airborne solid particles (aerosols) is soluble in water and can be oxidised within airborne water droplets producing sulphuric acid. This acidic pollution can be transported by wind over many hundreds of kilometres and is deposited as acid rain.

Is sulfur dioxide a primary pollutant?

Primary pollutants the beginning of the chain

It is a precursor of CO2 and ozone. Sulfur dioxide (SO2) which reaches the atmosphere mainly as a consequence of human activities such as the burning of coal or oil. Natural sources such as volcanoes also contribute a remarkable percentage.

Is Sulphur dioxide a greenhouse gas?

While sulfur dioxide isn’t a direct greenhouse gas like carbon dioxide or methane it is considered an indirect greenhouse gas. Sulfur dioxide is regarded as an indirect greenhouse gas because when coupled with elemental carbon it forms aerosols.

Is Sulphur dioxide a Vapour?

Sulfur dioxide has a pungent smell like nitric acid.

Sulfur dioxide.
Boiling point −10 °C (14 °F 263 K)

How is Sulphur dioxide removed from water?

Chlorine bleach can effectively remove medium to high levels (over 6 mg/l) of hydrogen sulfide. The chlorine in the bleach chemically reacts with (oxi- dizes) the hydrogen sulfide eliminating the “rotten egg” odor. Chlorine bleach also reacts with iron or manganese and disinfects water supplies.

What is wet FGD?

Wet FGD. The process of wet scrubbing typically utilizes an alkaline-based slurry of lime to scrub gases. A shower of lime slurry is then sprayed into a flue gas scrubber where the SO2 is absorbed into the spray and becomes a wet calcium sulfite. One by-product of that sulfite is it can be converted to salable gypsum.

How is SO2 formed?

Sulfur dioxide SO2 is a colorless gas or liquid with a strong choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum copper zinc lead and iron) that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid.

Is sulfur dioxide water soluble?

What does sulfur dioxide react with?

Sulphur dioxide is a dense colourless gas which is soluble in water and has a suffocating and unpleasant smell of burnt matches. … This is possible as UV radiation in the upper atmosphere catalyses the reaction between sulphur dioxide and oxygen to produce sulphur trioxide which goes on to react with water.

Which of the following is a chemical change water vapor in the air turns to liquid water in the form of rain?

Condensation is the process of water vapor turning back into liquid water with the best example being those big fluffy clouds floating over your head. And when the water droplets in clouds combine they become heavy enough to form raindrops to rain down onto your head.

What is observed when carbon dioxide is passed through lime water in excess also write the chemical equation for the reactions that take place?

When excess of carbon dioxide gas is passed through lime water then the white precipitate calcium carbonate formed first dissolves due to the formation of a soluble salt calcium hydrogen carbonate (Ca(HCO3)2 and the Solution becomes clear again. CaCO3 (s) + H2O(l) + CO2(g) ——> Ca(HCO3)2.
