Why is sulfur dioxide produced?

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. Sulfuric acid is a major component of acid rain.

What happens when a hydrocarbon is burned?

Burning hydrocarbons in the presence of oxygen (O2) produces carbon dioxide (CO2) and water (H2O). If there is too much carbon or too little oxygen present when hydrocarbons are burned, carbon monoxide (CO) may also be emitted. Sometimes unburned hydrocarbons are released into the air during incomplete combustion.

How is carbon sulfur dioxide produced?

. It is a toxic gas responsible for the smell of burnt matches. 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.

Is sulfur dioxide caused by combustion?

Sulfur dioxide (SO2) is one of the hazardous environmental pollutant gases and mainly emitted from the combustion of fossil fuel and eruption of volcanoes.

What happens when sulphur dioxide is heated?

Sulphur dioxide gas can be made directly by heating its constituent elements. Burning molten sulphur in either air or pure oxygen leads to a reaction, which produces a pale blue coloured flame.

Why is sulphur removed from fuels before they are burned?

When sulphur is burned, it produces sulphur dioxide. If this gets into the atmosphere, it can cause what is called ‘acid rain’. Therefore, wherever possible, we want to remove sulphur from fuels before we burn them.

What is produced when a hydrocarbon burns in air a component?

Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat. Hydrocarbons are molecules consisting of both hydrogen and carbon.

Why are hydrocarbons flammable?

Hydrocarbons are flammable because the carbon in their structure is in the most reduced form.

Why do some fuels produce Sulphur dioxide and nitrogen dioxide?

Answer: Sulfur dioxide comes from the burning of coal and oil. Nitrogen dioxide comes from the burning of fossil fuels (like gasoline).

How Sulphur dioxide is prepared in laboratory explain the bleaching property of Sulphur dioxide?

Preparation of Sulphur Dioxide In the laboratory, sulphur dioxide is prepared by the reaction of metallic sulphite or a metallic bisulphite with dilute acid. For example, a reaction between the dilute sulphuric acid and sodium sulphite will result in the formation of SO2.

Why does burning fossil fuels produce sulfur dioxide?

Many fossil fuels contain sulfur impurities. When these fuels are burned, the sulfur is oxidised to form sulfur dioxide.

Why Sulphur dioxide is a pollutant?

Sulphur dioxide (SO2 expressed as SOx) has long been recognized as a pollutant because of its role, along with particulate matter, in forming winter-time smog. Studies indicate that SO2 causes nerve stimulation in the lining of the nose and throat.
