What dark crystals turn into purple vapour when they are heated?
Amethyst crystals are known to turn into purple vapour when they are heated. This phenomena is due to the presence of iron impurities in the crystal structure of amethyst that react to heat by creating the purple coloring.
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.
You placed several crystals of iodine in a iodine chamber and covered it with a watch glass then you placed a white paper behind the chamber what will happen?
When iodine crystals are placed in an iodine chamber and covered with a watch glass, iodine vapor will sublimate and form a visible purple vapor inside the chamber. The white paper placed behind the chamber will allow the purple iodine vapor to be more easily visible against the contrast of the paper.
Are iodine crystals purple after sublimation?
Iodine crystals are not purple after sublimation. They are typically a deep blue or violet color.
Is black crystals of iodine turning into purple vapour of iodine a physical change or a chemical change?
The transformation of black crystals of iodine into purple vapor of iodine is a physical change. This is because the change does not involve a change in the chemical composition of iodine; it only involves a change in the physical state from solid to gas.

What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a purple-black non metal that changes to a deep purple gas when heated.

Iodine crystals are not purple after sublimation. They are typically a deep blue or violet color.
Is chemical change a black solid when heated changes into a purple gas?
When it is iodine (I2) it is only physical sublimation of the black (metallic shiny) I2 crystals into purple heavy gas clouds or fumes
Purple colored crystals that are added to water to kill germs?
Most likely crystals of Iodine. Iodine is known for its anti-bacterial properties.
Is black crystals of iodine turning into purple vapour of iodine a physical change or a chemical change?
The transformation of black crystals of iodine into purple vapor of iodine is a physical change. This is because the change does not involve a change in the chemical composition of iodine; it only involves a change in the physical state from solid to gas.
What element is is shiny black solid but gives off a purple vapor when heated?
Iodine on heating gives off dense purple vapor.
What black solid forms a purple vapour when heated gently?

What are iodines natural properties?
Iodine is water insoluble and turns black when exposed to light, Iodine is used in the diet and if we dont get enough iodine we may get impaired physical development in children. Iodine is a halogen so is toxi and can be used to kill bacteria. Iodine can also tell you whether a substance has starch or not in it.
How does a solid iodine change when it is heated?
Solid iodine sublimes directly into a purple-red gas when heated, without passing through a liquid phase. The purple-red gas will turn back into solid iodine upon cooling.
