name the process depicted by the above figure divide find the process why is cotton plug inserted in the steam of upper end of the funnel what may happen if sodium chloride is taken instead of Ammonium Chloride
Answers
Answer:
the process is crystallization and nothing will happen to sodium chloride which take it instead of Ammonium Chloride
hope this helps you and market as a brainiest answer please
You can select the mixture from the ‘Select the mixture’ drop down list.
Step 1: Sublimation
You can separate the sublimating substance (Naphthalene / Anthracene / Camphor / Ammonium chloride) from the mixture through the process of sublimation.
To start sublimation, click on the ‘Start Sublimation’ button.
To heat the mixture in the china dish, drag the china dish over the Bunsen burner.
Drag the glass funnel over the china dish and cover it, to collect the fumes of the sublimating substance.
You can go to the next process by clicking on the ‘Next’ button.
Drag the spatula into the finnel to collect the sublimed substance sticking inside it.
Once collected, drag the spatula back to put the substance in the watch glass.
You can click on the inference icon to see the inference.
Step 2: Filtration
You can separate soil / sand from the mixture through the process of filtration.
Drag the china dish towards the beaker containing water to transfer the mixture into it.
Click on the glass rod to stir the contents in the beaker.
To filter the contents in the beaker, drag it towards the funnel.
You can go to the next process by clicking on the ‘Next’ button.
To collect the soil / sand from the funnel, drag the spatula towards it.
Once collected, drag the spatula back to put the substance in the watch glass.

Step 3: Evaporation
You can separate sugar / salt from the mixture through the process of evaporation.
Drag the beaker towards the china dish to pour the contents of the beaker into the china dish.
Wait for sometime until the water evaporates.
Drag the spatula towards the china dish to collect the sugar / salt from the china dish.
Once collected, drag the spatula back to put the substance in the watch glass.

Click on the ‘Reset’ button to redo the experiment.
Note: Click on the ‘HELP’ button to see the instructions.
Precautions:
Always heat china dish on a wire gauze.
Plue the opening of the stem of the funnel with cotton while heating substances which sublimate.
Always separate sublimate from the mixture first or before dissolving salt in water.
While filtering a solution drop the contents along a glass rod into the funnel.
