Pure iodine is violet. It can act as an electron acceptor (an acid/ oxidizer <-- because it is taking negative charges (aka electrons) from something, leaving that something with an overall positive charge). 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. In my experience, the iodine turns water dark brown/ orange.

What color is iodine on litmus paper?
The water solution of iodine turn blue litmus paper to red.
I2 solven the why is show different colour inorganic chemistry?
Iodine dissolved in an organic solvent like hexane shows a different color compared to when it is dissolved in water due to differences in the solvent environment. In hexane, iodine exists as a nonpolar molecule, resulting in a purple color, while in water, it forms an iodine-water complex that gives a brown color. The solvent influences the electronic environment around the iodine atoms, leading to the observed color variations.
What substance does Iodine test for?
Iodine is commonly used to test for the presence of starch. When iodine comes into contact with starch, it turns from its amber color to a blue-black color. This color change indicates the presence of starch.
What color is iodine afer adding to filter paper?
Solid iodine is gray.
What substances are responsible for the different colors of the solution after the iodine test?
The iodine test primarily detects the presence of starch. When iodine (Iā) interacts with starch, it forms a blue-black complex due to the helical structure of amylose. If there are no starches present, the solution may remain yellow-brown, which is the color of iodine in water. Other substances, such as proteins or sugars, may also influence the color but do not produce the characteristic blue-black color associated with starch.
What happens when you add iodine with water?
When iodine is added to water, it forms a solution where the iodine molecules dissociate, producing a characteristic brown color. This color is due to the interaction of iodine molecules with water molecules.
What happens when iodine and water get mix together?
When iodine is mixed with water, it initially forms a solution with a characteristic brown color. Over time, the iodine will partially dissolve in the water, resulting in a mixture of iodine molecules and water molecules. This forms an iodine solution, which can then be used for various applications such as testing for starch presence.
Colours of solutions when iodine dissolves in it?
Iodine typically imparts a dark purple or brown color when it dissolves in solutions such as water or alcohol. The intensity of the color may vary depending on the concentration of iodine in the solution.
What color is Lugol's iodine?
The color of the chromosomes stained in a onion cell is usually a deep purple.
What happens when you mix startch and water substance with iodine?
Iodine will color the hydrated starch to very dark purple black
What substance turns dichloromethane to a violet color?
Bromine water turns dichloromethane to a violet color.
What will happen when you put a cornstarch in a plastic with water and dip it to the iodine?
Blue color
Does bacon have iodine color?
Bacon does not have iodine color. Iodine is a chemical element that is not naturally present in bacon.
What happens when iodine crystals are placed in water?
When iodine crystals are placed in water, they slowly dissolve to form an iodine solution. This solution will have a characteristic brown color, indicating the presence of iodine. Iodine is sparingly soluble in water, so the reaction may take some time to reach equilibrium.
Why does water turn brown when mixed with iodine?
When iodine is mixed with water, it forms a solution that appears brown due to the interaction between iodine molecules and water molecules. The brown color comes from the absorption of light by the iodine molecules, which causes them to appear brown to our eyes.
