Reagents

1 | 2 | | #15211

Reagents are a type of chemical which react to a specific compound, typically changing color or opacity when that compound is present. Usually, you add a few drops of a reactive chemical into a container of your sample, and look for a color change. Some reagents are dried onto flat strips or put inside glass tubes (for air testing).

Activities

Reagents are a really broad category, but some techniques related to them may be usable for various target chemicals.


Activities should include a materials list, costs and a step-by-step guide to construction with photos. Learn what makes a good activity here.
