Experiments of sublimation using some chemicals?

Answer 1

A simple experiment to show/prove sublimation is by using pottasium permangenate(solid) . All you need is a conical flask with a fairly long neck. Drop the pottasium permangenate into the conical flask and seal the mouth of the flask. Hold the flask to a flame from a bunsen burner. The heat from the burner should make the pottasium permangenate sublime into it's gaseous form producing a purple coloured gas. Then once it reaches the neck of the flask it will lose it's heat and cool down to form pottasium permangenate crystals.

And there you have it!

A simple experiment of sublimation.....

Answer 2

One common experiment with sublimation involves observing the sublimation of iodine crystals. When heated, solid iodine undergoes sublimation to form purple vapor without melting into a liquid state. Another experiment involves studying dry ice (solid carbon dioxide) sublimation, where it directly transitions from a solid to a gas at room temperature, producing a smoky effect. These experiments showcase the unique characteristics of sublimation, where a substance transitions directly from a solid to a gas without passing through the liquid phase.
