Using the Erlenmeyer flask and its contents from part A, continue with
these steps:
1. Heat the flask on a hot plate or in a microwave oven. Gently swirl
the flask at regular intervals until the crystals of sodium acetate
dissolve completely.
2. Make sure that all the sodium acetate is dissolved and no crystals
remain inside the flask. Once all the crystals are dissolved, remove
the flask from the heat. A.To avoid burns, be careful when working
with the hot plate and while handling the hot flask.
3. Allow the flask to cool for at least 30 minutes on a heat-resistant
surface without disturbing it. The flask should now be at or near
room temperature.
Before it was heated, the flask and its contents were at room
temperature. With regard to appearance, how are the contents of the
flask different from before they were heated and cooled?

Before heating, there were crystals of sodium acetate in the solution; after heating and cooling, the cystals disappeared indicating that the solution is a supersaturated solution.

What are supersaturated solutions?

Supersaturated solutions are solutions which contain more solute than they can actually dissolve at that temperature.

The heating and cooling of sodium acetate is the process of preparing a supersaturated solution of sodium acetate.

Before the heating, there were crystals of sodium acetate in the solution which then disappeared after heating and cooling, indicating that the solution is supersaturated.
