 Welcome back to Kids Find Science. My name is Ken. Today's experiment is what color is iodine? As always, adult supervision is required. What you need for this experiment is iodine, baby oil, water, and a 20 ounce bottle. So to set up this experiment, we take a bottle, a 20 ounce bottle, 503 milliliters, and fill it halfway with regular tap water. And then we're going to put iodine in the bottle until it looks like the color of tea. So I'm just using a pipette, but you're going to see that it's not, it's taken a little bit too long. So at the end of the day, I'm going to probably just have to pour it in because it's taking some time here. Give it a couple more squirts to see if that works. It's starting to look a little brown as it's coming in, a brownish orange color, right? So it's a lot darker in the cup, the iodine. Let me just pour a little bit in here. And you'll see we get a little bit more of that brown tint tea color. And so once we get that, then we're going to add baby oil. So you're going to want to tilt the bottle because you don't want to just do want it on the surface. And you're going to tilt it so it just gets about, you know, one centimeter, just a clear surface on the top like that. So now you can see there's a surface on it. And there's a separation with the baby oil and the iodine and water on the bottom, you can see right here. So it's a clear with the baby oil. And then the water and iodine are mixed into that tea color right there. Now we're going to take the lid. Hopefully you kept that from the bottle. I'm going to put that on tightly. And you're going to want to shake this for around 30 seconds until it's completely mixed up as much as you can. So you're going to start seeing it starting to turn like a purple color. And that's pretty cool. And we're going to let it sit there. And I'm going to explain the science behind this. This is truly an amazing experiment. Vividly demonstrates the non-polar nature of iodine, the iodine slightly soluble in water, but much more soluble in oil. You're going to see a color change in the solution and learn how this chemistry explains this magical result, right? So the experiment works because iodine is brown when it's dissolved in water and purple when it's dissolved in oil. Pure iodine is violet, but when it dissolves in water, it accepts an electron from the oxygen atom, affecting how it absorbs light. When we shook the bottle really hard, the iodine leaves the water and dissolves in the oil. This returns to its purple color. Reason the iodine molecules leave the water is to dissolve in the oil is due to how the polarity affects the solubility. Water is polar. It has an uneven distribution of electrons. Oil is non-polar, so the electrons in the molecules of the substance are distributed evenly. Iodine is also non-polar molecule, so therefore it's also soluble in oil. I hope you enjoyed this video.
