Precipitation II

Precipitation reactions occur when cations and anions in solution combine to form an insoluble solid called a precipitate. This film shows 6 different precipitation reactions recorded with a macro lens. If you think precipitation reactions just mean the cloudy liquid inside a test tube, think again! (Photography: Yan Liang)

Teachers can download a Worksheet for using this film in classrooms.

You may wonder, what does "II" mean in the film name? Well, there is a film (below) called Precipitation from Beautiful Chemistry three years ago.
