purple.
No
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.
YES
I don't know what these samples are of, but somethings just dissolve in oil but not in water. That's one of the properties they have.
halide ions strongly interact with the counter-ions. However, mineral oil is non-polar. To dissolve the halide ions (and the counter-ions) into mineral oil would drastically raise system energy. Thus it does not work. More simply, halide ions have a charge and won't easily dissolve in non-polar substances, since like-dissolves-like.
Yes, mineral oil is an oil used as a laxative and to seal wood used in food preparations such as the wood of a cutting board. Mineral spirits are used to thin or dissolve oil based paints and would not be safe to use around food.
The solubility in most of these is quite low. (Please see the link.)
Polar substances are miscible (will dissolve) in each other and non-polar substances will dissolve in each other. "Like dissolves like!" Mineral oil is non-polar. Hexane is a six carbon chain and is also non-polar. Water on the other hand is polar because it contains an electronegative oxygen.
Iodine is soluble in oil.
oil and latex are nonpolar molecules so they are able to interactwhich causes it to dissolve while polar molecules cant interract with non polar so water wont dissollve it.
Fresh, clean mineral oil is transparent and either colorless or a light golden color.
which have higher iodine, Fat or oil?
