Corrosive substances are materials that can damage or destroy living tissue and other materials through chemical reactions. Common examples include strong acids like sulfuric acid and bases like sodium hydroxide. These substances can cause severe burns, so it's important to handle them with care and use protective gear, such as gloves and goggles. In addition to harming people, corrosive substances can also damage metals, plastics, and other materials. For instance, when rust forms on iron, it is a result of corrosion caused by moisture and oxygen. Proper storage and disposal of corrosive materials are essential to prevent accidents and protect the environment.
