Product introduction: Sulfur dioxide is a common, simple, and irritating sulfur oxide with the molecular formula of SO2. It is a colorless gas and one of the main atmospheric pollutants. When a volcano erupts, it emits this gas and produces sulfur dioxide in many industrial processes. Due to the fact that coal and petroleum usually contain sulfur, sulfur dioxide is generated during combustion. When sulfur dioxide dissolves in water, it forms sulfite. If sulfite is further oxidized under the presence of PM2.5, it will quickly and efficiently generate sulfuric acid (the main component of acid rain). This is one of the reasons for concern about the environmental effects of using these fuels as energy.
