What is the purple gas which fills the test tube when heating an iodine?
The purple gas formed when heating solid iodine in a test tube is iodine vapor. Iodine sublimes directly from a solid to a gas when heated, turning into a purple gas that condenses back into solid iodine crystals when cooled.
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.
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.
Why iodine exist in solid state but it is a gas?
Iodine sublimes (i.e., goes from a solid to a gas) at room temperature and atmospheric pressure. However, it will exist as a solid for a very long time if it is kept in a closed container. As the iodine solid sublimes, the pressure will increase slightly within the closed container which will cause the iodine gas to reach an equillibrium state with the solid iodine (i.e., there will not be an increase in the amount of iodine gas in the container).
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.

What state is iodine at room temperature?
Iodine is a solid when at 25 degrees centigrade (room temperature)
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 colorless gas?
No, iodine is a violet coloured solid on heating it sublimed into violet gas.

What gas is produced when iodine are heated?
When iodine is heated, it sublimes directly from a solid to a purple gas. The gas produced is diatomic iodine molecules (I2).
Does solid iodine give blue gas on sublimation?
Yes, solid iodine sublimes directly to a purple vapor, not blue.
Which halogen goes from the solid phase directly to a gas?
Iodine is the halogen that sublimes directly from a solid to a gas at standard pressure and temperature.
What are the names of the three states of iodine?
The three states of iodine are solid, liquid, and gas. At room temperature, iodine is a solid with a dark purple color. When heated, it sublimes directly from a solid to a purple-violet gas.
What substance that changes from solid to gas?
Iodine
