- Definição1
- A substance used to change the speed or rate of a chemical action without being chemically changed itself. Water functions as a catalyst in the process of iron turning into rust (iron oxide). Dry iron does not rust nearly as fast as iron with water on its surface. The water itself is not affected, but the iron unites with oxygen from the air to become iron oxide, or rust.
