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 ...

NOTE: Make sure that you have adult supervision for this experiment AND wear your safety glasses! Add 1 teaspoon of liquid starch to 2/3 cup of water in a small glass or container. In another small ...

This experiment is about much more than just watching Iodine solution turn royal blue from reddish brown. Try this experiment at home with the kids to introduce them to the basic tenet of physics -- ...

Counterfeit detector pens use a starch-iodine reaction to identify fake bills. But could you fool them with chemistry? In today’s episode, we dive into the chemistry of iodine, its color and its clock ...

A new experiment conducted at the world's largest particle physics laboratory, demonstrates the mechanism for how the gas-phase form of iodine -- known as iodic acid -- forms, and suggests it has a ...

Pierangelo Metrangolo and Giuseppe Resnati celebrate the bicentenary of the discovery of iodine — a good time to also bring to its conclusion an international project that aims to define and ...
