Which halogen sublimes to violet vapours?
iodine is the only halogen in solid form. so it is the halogen which gives violet vapours on sublimation...
What is appearance crystal iodine?
The appearance of iodine crystals: lustrous, metallic, gray.
Name an element that exists in a crystal lattice at stp?
iodine
What happens when you add iodine crystal and chloroform?
iodine is soluble in CHCl3. Liquid become purple in color.
What is characteristics of iodine crystal that make it soluble to water?
Atoms and crystalline
A substance that exists as a solid at ordinary temperature but changes to vapour on heating?
Iodine and ammonium salts sublime, their vapours then turn back into solids when cooled down. To see the sublimation, heat some iodine in a china dish and place a funnel upside down above the vapours (violet). The heated vapours become solid on contact with the funnel wall.
When iodine is heated?
when iodine is heated it gives voilet vapours
Which halogen sublimes to violet vapours?
iodine is the only halogen in solid form. so it is the halogen which gives violet vapours on sublimation...
What vapor colors does iodine have?
violet vapours
What is an example of the gaseous state of matter?
Examples: water vapours, nitrogen, helium, iodine vapours, oxygen, xenon etc.
Why is Iodine used in Gram staining?
Iodine is added as a mordant to enhance crystal violet staining by forming a crystal violet-iodine complex.
What is the difference between iodine crystals and iodine solution?
Iodine crystal is solid Iodine. Iodine solution is when Iodine crystals are dissolved in water.
Is iodine crystal an ionic or molecular crystal?
it has molecular crystals
Describe the bonding in a crystal of iodine?
iodine is made from diatomic iodine molecules,the two iodine atoms are covalently bonded with each other.the iodine molecules have dispersion forces so,the crystal is made from the dispersion forces between the iodine molecule.
What are the Spray reagents for visualize colerless compound in TLC?
Iodine vapours can be used as spray reagent in TLC
