👉 Sulfurize is a chemical reaction that involves the transformation of sulfur gas (H2SO4) into sulfuric acid (H2SO4), which is an acidic solution. The reaction occurs when sulfur dioxide (SO2) reacts with water vapor (H2O) to form sulfuric acid and oxygen gas (O2). This process is known as the reduction of sulfur dioxide. Sulfuric acid has a high corrosivity, which means it can corrode metal surfaces.
