What else can I help you with?
What do you call when iodine crystals turn to iodine haze?
You think probably to sublimation of iodine.
How would you separate iodine crystals from mixture of iodine and sand?
One method to separate iodine crystals from a mixture of iodine and sand is by using sublimation. Heat the mixture, and the iodine will sublimate (turn into gas) leaving the sand behind. The iodine gas can then be collected and cooled to form iodine crystals.
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).
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.
What is Iodine at 120 celcius?
At 120 degrees Celsius, iodine is in its liquid state. When heated further, it will eventually reach its boiling point of 184 degrees Celsius and turn into a gas.

How do you make iodine gas back to solid iodine?
After the iodine is in gaseous form, contain and cap it off with an iced container to recollect it and turn it back into a solid by allowing the gas to rest. The temperature then has to be below 113.5°C in order to solidify.
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 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).
What happens when you burn an iodine crystal?
when iodine crysatals are heated, they turn from a solid into a gas (vapour). They start a black colour and as they gradually turn into a gas, they turn to a purple colour. At the end, there are no crystals left.
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.
What is the common property of iodine and naphthalene?
they both sublime, in which the solid particles will change directly into gas.
What is Iodine at 120 celcius?
At 120 degrees Celsius, iodine is in its liquid state. When heated further, it will eventually reach its boiling point of 184 degrees Celsius and turn into a gas.
How does a solid iodine change when it is heated?
It gets further apart and turns into a pink purple colour
What noble gas comes before iodine?
The noble gas that comes before iodine is krypton.
What are examples of gases that turn to solids?
Iodine gas can return directly to its solid state by cooling it and/or putting it under pressure.
