What is the connection between sulfur dioxide and sulfuric acid?

The main connection between sulfur dioxide and sulfuric acid is that sulfur dioxide is a precursor in industrial production of sulfuric acid. There are two industrial processes for the production of sulfuric acid, which include oxidation of sulfur oxide to sulfur dioxide and subsequent combining sulfur oxide with water to form acid. Sulfry and sulfuric acid are also serious pollutants. They are the main contributors to acid rain.

sulfur dioxide (so _{2 ) - pungent, toxic gas - is made up of sulfur burning through the reaction of S + O 2 → SO 2 . It is also created by burning many sulfur -containing substances, such as hydrogen sulphide and various organic sulfur compounds found in fossil fuels. Heating of ore and minerals containing sulfur-for example, iron (FES 2 )-is another way to produce the gas: 3FES 2 + 8o The production of sulfur dioxideo A sulfuric acids form one of the most important industries of the chemical industry and are responsible for most of the world's sulfur production.}

sulfuric acid was produced in early times by distillation of iron sulphate II or "green vitriol" and later heating the salt mixture (nano _{3 ) and sulfur together with steam. In the 18th century, industrial production of sulfuric acid using sulfur dioxide using what was originally called the main chamber process. Sulfur dioxide was produced by sulfur burning or heating iron and oxidized to sulfur dioxide (so 3 ) using nitrogen oxide (not 2 ): So 2 + no Nitrogen oxide for the reaction was originally produced by the thermal decomposition of salty intestine, but later it was provided by ammonia using a catalyst. The reaction took place in the chambers lined with lead in which the water spray was directed, andHe dissolved sulfur oxide oxide to form sulfuric acid, which is collected at the bottom of the chamber.}

The

Main Chamber production method has now been mostly replaced by a contact process. This gives up the need for nitrogen oxide by reacting sulfur dioxide with air to form sulfur dioxide. Normally, this reaction is very slow; However, after using a suitable catalyst, it proceeds quickly. Platinum was an effective but modern contact process uses vanadium pentoxide.

sulfur dioxide and sulfuric acid, although they are of huge industrial importance, are also the main pollutants and are the largest sources of acid rain. In the air, sulfur dioxide is slowly oxidized to sulfur oxide, which reacts with moisture in the atmosphere to form diluted sulfuric acid. This may fall as sour rain, which can damage the growing life and stone buildings, or they may react with other pollutants to form sulphate particles that may act as condensing coresAnd they can play a role in creating a cloud.
