Iodine work as a modrant which helps in fixing the stain properly by making a compled compoun of stain and cell wall.
When iodine is heated does any iodine melt?
iodine is a substance that has an unusual property, it has the ability to sublimate, this means that it converts directly from a solid to a gas with no liquid stage at all. So no, no iodine will "melt" into a liquid, it will insted turn into a purple gas.

What is the common property of iodine and naphthalene?
they both sublime, in which the solid particles will change directly into gas.
What is the correct formula for potassium and Iodine?
Literally, the correct formula for potassium and iodine at standard temperature and pressure would be " K and I2". The formula for the compound formed between potassium and iodine, however, is KI.
What is iodine vapour?
A "vapor" in chemistry is always the gas phase of a substance that is more familiar in one of its condensed phases: liquid or solid. Therefore, iodine vapor is the gas phase of the element iodine, and has the same molecular composition as the solid, I2. Iodine is a solid at standard temperature and pressure, but sublimes directly to gas phase, without any intermediate liquid phase, at only moderately higher temperatures than the standard.
Iodine what is it's state of matter?

Which halogen goes from the solid phase directly to a gas?

Difference between iodometry and iodimetry?
When an analyte that is a reducing agent is titrated directly with a standard iodine solution, the method is called "iodimetry". When an analyte that is an oxidizing agent is added to excess iodide to produce iodine, and the iodine produced is determined by titration with sodium thiosulfate, the method is called "iodometry".
Why can gas iodine stick to fingerprints?
The gas iodine will stick to the fingerprints because they will crystallize when they come into contact with a cool surface. When heated, iodine directly changes into vapor.
What changes from a solid directly to a gas?
