Hot Ice Experiment

 Prepare the materials and apparatus as below:

(a) Sodium Acetate

(b) A beaker

(c) bunsen burner & wire gauze

(d) distilled water

(e) ice

 set up the apparatus as shown above

cool it down without disturbing it

this is what you can see after added crystal

1. Put 2 tablespoon of sodium acetate in a flask.
2. Heat gently and stir until the crystals of sodium acetate melt. Use a small amount of water to rinse down the inside of the flask.
3. Remove the flask from the heat and let it cool slowly without disturbing it.
4. Add one or two crystals (that’s right, it only take a single crystal) to the liquid in the flask. Don’t take your eyes off of the liquid as beautiful crystals begin to form inside the flask.
5. Feel the flask… it’s warm! The process of crystallization gives off heat. It’s said to be exothermic.
