Corrosion is a broad term that applies when something is being broken down due to a chemical reaction. Rust or wet corrosion is a specific type of corrosion where iron or steel reacts with water. Science teachers often find that over time, laboratory equipment made of metal may tend to look dull and have symptoms of corrosion. In fact, in certain instances, such equipment may become unsafe to use and provide bogus data results on student experiments. There are several strategies that can be used to address corrosion of lab equipment. This article describes some approaches to combating corrosion.
