This "iodine clock" experiment is so cool, we feel cheated that we never got to do it in high school chemistry lab. But it turns out the popular experiment is so simple to do — involving only a bit of ...

The iodine clock is a common chemistry experiment in which two clear liquids are mixed together to produce a dark, opaque color. But as you’ll see in this video, the speed at which this reaction ...

In this activity, students will perform three experiments using household ingredients to observe and record color changes, indicators that a chemical reaction has taken place. Students also will ...
