Kids Encyclopedia Facts
Reagents, such as sulfur (pictured), are the starting materials that are used in chemical reactions.

A reagent is a chemical used to test for other chemicals. For example, potassium dichromate is used to test for alcohol, and nitric acid can be used to test for gold. Normally there is an obvious change, such as a color change or the formation of a solid substance.
