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 is the difference between iodine crystals and iodine solution?

Iodine crystals are solid, crystalline form of elemental iodine, while iodine solution is a liquid mixture of elemental iodine and either alcohol or water. Iodine crystals are typically used for storage and long-term preservation, while iodine solution is commonly used for disinfection and medical purposes.

Add a drop of iodine to both a distilled water test tube and to the test tube containing the starch solution in the test tube What do you observe?

The starch solution will turn black, while the distilled water will remain brown, the same colour as the iodine. This is actually because water, normally used as a control, does not contain any starch and as we know, the iodine test is highly specific for the presence of starch hence no colour change other than iodine dissolving in water to form an iodine solution contrary to starch which we know complexes with iodine, to form starch-iodine complex forming the blue-black colour observed
