Why does solid iodine not stick to fingerprint when heated?
that is because of iodine is solid and when it heated it mulicules moves faster after that your finger prints will not be seen and even did not stick from:bloodboilz_15@yahoo.com pake add me
Explain why the solid iodine did not stick to the finger prints but it could when it was heated?
Solid iodine sublimes at room temperature, meaning it goes directly from a solid to a gas without melting. As a result, it does not stick to surfaces like fingerprints because it does not become liquid when in contact with the skin. When heated, the iodine turns into a gas, which can then interact with the oils and sweat in the fingerprint, making it visible.
Colour of iodine solid?
The color of solid iodine is a dark purple.
At STP which element is a solid hydrogen or iodine?
At standard temperature and pressure (STP), iodine is a solid while hydrogen is a gas.
Is Iodine a soild or gas?
Elemental iodine is a solid. But it is a volatile solid in that chemists will use solid iodine in a chamber to "iodine stain" substances in thin layer chromatography. Thus iodine is like having a volatile solid.

How do you get pure dry iodine from a mixture of iodine and sand.?
Well every school kid knows about the 'cold finger' separation technique. Iodine changes from a solid straight to a gas when heated. It sublimes. So heat the sand/iodine mixture in a pyrex tube or flask which has a 'cold finger' inserted. The hot iodine gas will rise, hit the cold finger and form pure solid iodine crystals on the cold finger. Collect from the finger. This really is bog standard school kid chemistry.

What state is iodine at room temperature?
Iodine is a solid when at 25 degrees centigrade (room temperature)
The chemical equation of iodine solid to gas?
The chemical equation for the sublimation of iodine solid to iodine gas is: I2(s) -> I2(g). This represents the process in which solid iodine directly transforms into iodine gas without going through a liquid phase.
What is iodine's physical state at 20 degrees C?
Iodine is a solid at 20 degrees Celsius.
In what form does iodine exists?
Pure iodine at room temperature is a highly volatile solid.
Iodine liquid or solid?
Iodine is a solid at room temperature and pressure. It sublimes directly from a solid to a purple vapor without melting.
What state is iodine at -10 degrees?
Iodine is a solid.
