Sulfur dioxide (chemical formula: SO2), also known as sulfite, is the most common sulfur oxide and the main component of sulfuric acid feed gas. Sulfur dioxide is colorlessgasIt has a strong pungent odor and is one of the main pollutants in the atmosphere. During volcanic eruptions, this gas is released, and in many industrial processes, sulfur dioxide is also produced. Due to the presence of sulfur compounds in coal and petroleum, sulfur dioxide is generated during combustion. When sulfur dioxide dissolves in water, it willformationSulfuric acid (the main component of acid rain). If SO2 is further oxidized in the presence of a catalyst (such as nitrogen dioxide), sulfuric acid (H2SO4) will be generated, which can corrode the skin when used with caution.
