Preform an activity to show sublimation of aluminum cloride |
|
Answer» Take some ammonium chloride and POWDER it. Keep the powder in a CHINA dish. Now cover the china dish with an inverted funnel as shown in the illustrated figure. Then close the end of the funnel with a piece of cotton. Now place the dish on a wire mesh kept on a TRIPOD stand to heat it by a burner. You will notice that the FUMES (i.e., vapours) of ammonium chloride are seen in the funnel above the dish. Thus, ammonium chloride on heating, changes directly from SOLID to gaseous form which shows the sublimation of AMMONIUM CHLORIDE. |
