What color is iodine when mixed with dichloromethane?
When iodine is mixed with dichloromethane, the resulting color is purple or violet.
What color does CaSO4 turn into with iodine?
When calcium sulfate (CaSO4) is mixed with iodine, it forms a yellowish-brown color due to the reaction between the calcium sulfate and iodine.
Does sugar turn blue when mixed with 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.
What color is iodine when mixed with water what color is iodine when mixed with mineral oil?
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.
What happens when you mix sugar and iodine?
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.
What color is iodine when mixed with dichloromethane?
When iodine is mixed with dichloromethane, the resulting color is purple or violet.
Why does petrol change color when mixed with iodine solution?
Petrol changes color when mixed with iodine solution due to covalent bonding.
What is the color of iodine when mixed with rice?
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.
When water and decane are mixed which layer will float on top?
Water is denser than decane, so the water layer will sink to the bottom while the decane layer will float on top.
What is the color of iodine when mixed in carbon tetrachloride?
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
What color does CaSO4 turn into with 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.
What happens to cornstarch when mixed with an indicator what color does it turn?
When cornstarch is mixed with an iodine solution, it forms a blue-black complex. This color change occurs because the iodine molecules fit into the helical structure of the amylose component of starch. In the absence of iodine, cornstarch remains white and powdery, but the addition of iodine reveals its presence through the distinct color change.
What happens when sugar and iodine is mixed?
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.
What color is iodine mixed with calcium carbonate?
When iodine is mixed with calcium carbonate, the iodine typically appears as a violet or dark purple color due to its molecular form. However, the calcium carbonate itself is white, so the overall appearance of the mixture can vary depending on the amount of iodine used. If the iodine is in excess, the mixture will have a prominent purple hue, while smaller amounts may result in a more subdued color.

What color of iodine mixing with hexane?
When iodine is mixed with hexane, it typically results in a violet or purple color in the hexane layer. This occurs because iodine is more soluble in non-polar solvents like hexane compared to polar solvents. The distinct color is due to the formation of iodine molecules that are dissolved in the hexane, which reflects the characteristic color of iodine.
