What happens if you mix water and iodine? – AnswersToAll
2021-3-28 What happens if you mix water and iodine? When iodine and starch are dissolved together in water, gooey starch molecules instantly trap iodine ions close together to create a dark, blueish-black color. (Dripping liquid iodine onto a potato will turn it the same color, due to all of the spud’s starch.)

Iodine and Starch Experiment Iodine Experiment Starch ...
So, iodine is prepared by dissolving it in water in an aqueous solution of potassium iodide. This results in a linear tri-iodide ion (I3−) complex in iodine which is soluble. This tri-iodide ion (I3−) slips into the coil of the starch causing an intense or deep blue-black color.

When starch is mixed with iodine in water, an intensely colored starch/iodine complex is formed. Many of the details of the reaction are still unknown. But it seems that the iodine (in the form of I 5-ions) gets stuck in the coils of beta amylose molecules (beta amylose is a soluble starch). The starch forces the iodine atoms into a linear ...

QUANTIFICATION OF SOLUBLE STARCH FROM FRESH
2020-5-20 The presence of starch can be measured by its reaction with iodine. Starch and iodine form a dark-blue complex with an absorbance maximum at 600 nm [1]. This application note describes a simple procedure to extract soluble starch from fresh potatoes. The amount of soluble starch extracted is then measured with the Photopette® at 600 nm.

What happens when you mix cornstarch and oil?
2020-4-26 As you mix it all together observe what's happening in your container. You're probably noticing the formation of a thick, gooey liquid. The water and oil are giving the cornstarch particles something to move around in so they can start forming those long chains of molecules. Scientists call such substances “polymers”.
