Transcript of Science project: Hot Ice
as sodium acetate. Purpose The purpose is to produce a useful product sodium acetate. Science Project
2012-2013 Materials One liter of vinegar
A medium pot
and measuring spoons. Procedure Variables Dependent variables:
measuring spoons Step 1: Pour six liters of vinegar into the pot.
Step 2: Slowly add 3 tablespoons of baking soda and stir.
Step 3: Let solution boil until a thin layer of crystal forms on the surface.
Step 4: Pour the solution in a bowl and cover with plastic wrap and let solution cool until room temp.
Step 5: Put solution in refrigerator for 1 hour and keep wrapped.
Step: 6: Take out solution and then touch or pour slowly on the plate and watch the crystals form. Resources http://www.drugs.com/pro/sodium-acetate.html

Touch: It had a greasy feel to it.
Taste: Taste was not appropriate for the project.
Sight: The liquid went throught different colors as it boiled. In the beginning it was clear, to a light amber, to a dark amber.
Sound: While I was mixing the vinagar and baking soda I could hear a sizzling sound. Results After I cooled the solution I began to pour it on a plate and then the crystals began to form and make a tower out of 'hot ice'. Conclusion In the end I got a perfect result of 'hot ice' or sodium acetate.
