What happen when hydrogen sulphide reacts with Sulphur dioxide?

Hydrogen sulfide reacts with sulfur dioxide to give H2O and S, H2S + SO2 = H2O + S(solid), unbalanced. Also, 3.0 L of H2S gas at 760 torr produced 4.8 g of sulfur.

What is the difference between hydrogen sulphide and sulfur dioxide?

The key difference between H2S and SO2 is that H2S has the smell of a rotten egg, whereas SO2 has the smell of a burnt match. H2S is a hydride of sulfur while SO2 is an oxide of sulfur. Moreover, both these gases have a pungent odour.

Which is more toxic H2S or SO2?

Hydrogen sulfide (H2S) is a poisonous chemical asphyxiate, similar to cyanide gas or carbon monoxide. It is much more dangerous than sulfur dioxide (SO2).

Is H2S to S oxidation or reduction?

Is HS + SO2 a redox reaction? Yes. H2S is oxidized to sulfur and SO2 is reduced to sulfur.

What happens when SO2 is passed through acidified H2S?

When SO2 gas is passed through saturated solution of H2S, the following reaction occurs SO2 + 2H2S → 2 H2O + 3S In this reaction, which substance is oxidized and which one is reduced.

What does Sulphur dioxide smell like?

It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of sulfur-bearing fossil fuels. Sulfur dioxide has a pungent smell like nitric acid.

Which gas gives the smell of rotten eggs?

Hydrogen sulfide is a colorless, flammable gas that smells like rotten eggs at low concentration levels in the air. It is commonly known as sewer gas, stink damp, and manure gas.

What happens when H2S is burned in air?

Slightly denser than air, it can be incredibly explosive. When burning with oxygen, hydrogen sulfide burns blue, to form sulfur dioxide, and water. It is somewhat soluble in water, and acts as a weak acid.

How do you neutralize SO2?

NaOH neutralizes the absorbed SO2, producing a mixture of soluble sodium salts. The carefully chosen packing material provides a large surface area for reaction. The scrubbing liquid, SO2 in solution, and salts fall into the tank and are removed.

What are the dangers of sulfur trioxide gas?

Acute inhalation exposure of sulfur trioxide may result in sneezing, hoarseness, coughing, choking, laryngitis, and respiratory tract irritation. Bleeding of nose and gums, ulceration of the nasal and oral mucosa, bronchitis, pneumonia, dyspnea (shortness of breath), chest pain, and pulmonary edema and respiratory failure may also occur.

What produces sulfer dioxide emissions?

oil and natural gas are the main source of sulfur dioxide emissions.

Is H2S hydrogen sulfide or dihydrogen sulfide?

pH of Hydrogen Sulfide Chemical formula: H 2 S Also known as: Dihydrogen monosulfide, Dihydrogen sulfide, Sewer gas, Sulfane, Sulfurated hydrogen, Sulfureted hydrogen, Sulfuretted hydrogen, Sulfur hydride, Hydrosulfuric acid, Hydrothionic acid, Sulfhydric acid

How does sulfur dioxide react with water?

Sulfur dioxide can dissolve in water to form an acid. This acid can react with calcium carbonate, causing it to become products that are not solids. As a result the mass of solid falls. This is the basis of the reactions caused by acid rain.
