How would you separate and purify constituents of mixture of salt of iodine?
To separate salt and iodine, you can use sublimation. The iodine will sublimate at room temperature, leaving the salt behind. To purify the iodine further, you can re-sublimate it by heating it gently and collecting the vapor to form pure iodine crystals.
Which halogen is a grey solid?
Iodine is a grey solid halogen at room temperature. It has a shiny appearance and can sublimate into a purple vapor when heated.
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.
Is iodine a brittle solid at room temperature?
No, iodine is a dark purple, shiny solid at room temperature. It has a characteristic metallic luster and can sublimate directly from a solid to a gaseous state.
Does iodine turn into vapour on heating?
Yes, iodine does sublimate directly from solid to vapor form when heated without turning into a liquid state. This is due to its relatively low melting point of 113.7°C.
What particles sublimate?
iodine

What is an example of sublimation that is not dry ice?
Iodine crystals will sublimate to iodine gas without going through a perceivable liquid state.
Which halogen is a grey solid?
Iodine is a grey solid halogen at room temperature. It has a shiny appearance and can sublimate into a purple vapor when heated.
What element readily sublimates under normal conditions?
Iodine is one of the easiest elements to sublimate.

How can you separate a mixture of iodine ammonium chloride and sand?
Add sufficient water to dissolve the ammonium chloride. Neither the iodine nor the sand will dissolve.Filter out the solids.Evaporate the ammonium chloride from the solution.Heat the solids gently in a retort to sublimate the iodine and recover it.
Does iodine turn into vapour on heating?
Yes, iodine does sublimate directly from solid to vapor form when heated without turning into a liquid state. This is due to its relatively low melting point of 113.7°C.
Does iodine lose its reactivity at high temperatures?
Iodine remains reactive at high temperatures due to its innate chemical properties. However, excessive heat can cause iodine to sublimate and transform into a gas, which may influence its reactivity in certain reactions.
Why does iodine have a smell?
Iodine has a distinct smell because of its vapor, which is a result of its ability to sublimate from a solid to a gas at room temperature. The scent is often described as pungent and similar to that of chlorine.
When iodine crystals are heated and cooled in a hot water bath what happens?
When iodine crystals are heated, they sublimate directly from solid to gas without melting. As the hot iodine gas cools, it reverts back to solid form on the cooler surfaces of the container, forming iodine crystals again. This process is called sublimation.
