Purple
When iodine is mixed with dichloromethane, the resulting color is purple or violet.
When calcium sulfate (CaSO4) is mixed with iodine, it forms a yellowish-brown color due to the reaction between the calcium sulfate and iodine.
Yes, sugar does not turn blue when mixed with iodine. Iodine reacts with starch, turning it into a blue-black color. Sugar does not contain starch, so it will not have a reaction with iodine in this way.
I think it depends on the mixtures. When I mixed a store bought solution of iodine (2.5% iodine and 2.5% potassium iodide) in water it was brown. But when I added heavy mineral oil and mixed them, the mineral oil layer was a brilliant pink/purple colour. Really impressive. NR Pure iodine is violet. It can act as an electron acceptor (an acid). When iodine is in a solvent that doesn't donate electrons it stays violet. When it is in water or ethanol the iodine accepts electrons from the oxygen atom which then affects the wavelength of visible light that it absorbs, this means that the colour changes.
When sugar and iodine are mixed together, the iodine will not react with the sugar. The iodine may simply dissolve into the sugar, giving it a purplish color. This reaction is purely physical and does not involve a chemical change.
When iodine is mixed with dichloromethane, the resulting color is purple or violet.
Petrol changes color when mixed with iodine solution due to covalent bonding.
When iodine is mixed with rice, it turns blue-black in color. This reaction occurs because iodine reacts with starch, which is present in rice, forming a blue-black complex.
Water is denser than decane, so the water layer will sink to the bottom while the decane layer will float on top.
depending on the amount of iodine or carbon tetrachloride, it will be eaith pink(more CCl4) or violet (otherwise) please correct me if i'm wrong
When calcium sulfate (CaSO4) is mixed with iodine, it forms a yellowish-brown color due to the reaction between the calcium sulfate and iodine.
Yes, sugar does not turn blue when mixed with iodine. Iodine reacts with starch, turning it into a blue-black color. Sugar does not contain starch, so it will not have a reaction with iodine in this way.
When sugar and iodine are mixed, the iodine will turn purple or black due to a reaction with the starch that is naturally present in sugar. This color change is commonly used as a simple test for the presence of starch.

When iodine is mixed with citric acid, the iodine can be dissolved or react with the citric acid to form iodine citrate. This reaction can alter the properties of iodine, such as its solubility, color, or chemical behavior.
Iodine and talc do not create a specific color when combined. Talc is a white or light-colored mineral, while iodine is a dark purple-black solid. When iodine is mixed with talc, the appearance would depend on the proportion of each substance used.
