Diagram of sublimation of ammonium chloride

Sign in Open App. Write the help of a labelled diagram describe in brief and activity to show sublimation of ammonium chloride? Most Upvoted Answer. Here is a brief description of the diagram: 1. Procedure: - Place a small amount of ammonium chloride in the round-bottomed flask. Labelled Diagram: The labelled diagram should clearly show the different components of the apparatus and the direction of gas flow. It should also indicate the heating source and the cooling arrangement. Place a small quantity of ammonium chloride in the test tube. Attach the glass funnel to the mouth of the test tube, ensuring a tight seal. Place the test tube in a beaker containing cold water or ice.

Observations: As the ammonium chloride is heated, it gradually sublimes, meaning it directly changes from a solid state to a gaseous state without passing through the liquid phase. Tutorialspoint Simply Easy Learning. View All Courses.

Ammonium chloride when heated decomposes into hydrogen chloride and ammonia. Experiment of sublimation of ammonium chloride. Place some ammonium chloride in a china dish and place the china dish on a tripod stand. The china dish is covered with an inverted glass funnel. A loose cotton plug is placed in the upper, open end of the funnel to prevent the ammonium chloride vapours from escaping into the atmosphere. The china dish is heated by using a burner. On heating, ammonium chloride changes into white vapours.

Some compounds are capable of sublimation, which is the direct phase change from solid to gas. Solid carbon dioxide is an example of a substance that sublimes readily at atmospheric pressure, as a chunk of dry ice will not melt, but will seem to "disappear" as it turns directly into carbon dioxide gas. Sublimation is an analogous process to boiling, as it occurs when a compound's vapor pressure equals its applied pressure often the atmospheric pressure. The difference is that sublimation involves a solid's vapor pressure instead of a liquid's. Most solids do not have an appreciable vapor pressure at easily accessible temperatures, and for this reason the ability to sublime is uncommon. Compounds that are capable of sublimation tend to be those with weak intermolecular forces in the solid state.

Place the sample to be sublimed in the bottom of the sublimation apparatus. Be sure to apply the vacuum first, then coolant. If cooled before the vacuum, condensation may occur on the cold finger. Delicately reinstate the air pressure, noting that an abrupt opening of the vessel will cause air to knock crystals off the cold finger.

Callanan and Smith, Callanan, Jane E. Follow Us. Kafafi B - John E. Ammonium chloride when heated decomposes into hydrogen chloride and ammonia. After heating, ammonium chloride is converted into vapor and gets deposited over the inner surface of a funnel; due to cooling. Place the test tube in a beaker containing cold water or ice.
