Rust Chemistry: How Does Rust Form?
When you hear the term “chemical reaction”, you might think of scientists in white lab coats mixing dark powders to create explosions. Maybe you think of the flurry of bubbles you saw when you mixed baking soda and vinegar in kindergarten. You probably don’t think of your bicycle rusting after you leaving it out in the rain—but rust is indeed the result of a chemical reaction!
A chemical reaction happens when one or more different substances is changed into something else. For instance, when baking soda is combined with vinegar, carbon dioxide gas—a new substance—is created. In a chemical reaction, our starting substances are called the reactants; the substances at the end are called products.
