Now those of you who know iodine and starch (and there are so many of you here that I really don’t know why you don’t form the Iodine-Starch Society), know that when iodine and starch get ...

Note: This demo has two parts, I & II. When ordering, please specify whether you want Part I, Part II, or both at the same time.IntroductionI. The reaction between iodate and bisulfite in acid medium ...

You can also use simple store bought chemicals like vitamin C, iodine, hydrogen peroxide and starch. A quick internet search will turn up multiple ways of performing the experiment.

It’s the starch in the porridge that picks up the iodine and makes a blue-black-colored complex. Starch and iodine are extremely sensitive mutual indicators. Starch molecules look similar to long ...

To do this, pour one half cup of distilled water into a disposable cup, add one half teaspoon (tsp.) of laundry starch solution and then add five drops of the iodine antiseptic solution.

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 ...
