Title: Home Experiment - need help
Post by: tarikmeisteryt on March 18, 2022, 09:24:08 AM
So basically our lab instructor told us to discuss and demonstrate a topic about these following topics with an actual experiment that can be done at home:

1. Intermolecular Forces of Liquids and Solids (Phase Changes & Phase Diagrams)
2. Acid-Base Titration & Concentration of Units
3. Colligative Properties of Nonelectrolyte and Electrolyte Solutions
4. Thermochemistry: Thermochemical Equations
5. Thermochemistry: Enthalpy and Hess's Law

I already have two initial ideas, although I'm posting this to ask for more input and suggestions:

1. In the Phase Changes topic, I want to do homemade ice cream with a catalyst of salt to demonstrate a variety of chemical reactions.

2. In the acid-base titration topic, inflating a balloon without helium using the reaction from caustic soda - NaOH of a drain cleaner (basic) and aluminum foil (amphoteric).

Can you do the titration with vinegar and baking soda to find the concentration of acid in the vinegar? It would be easier/safer.

Baking soda is a very poor titrant.

Most of experiments I can think of require a reasonably accurate thermometer, do you have one?

Yes your right.  I was just thinking along the lines of what would be more readily available in the home setting ( although now that I think about it, what I suggested would also require a balance and a couple pieces of glassware that most people probably dont have at home).
