Beginner chemistry experiments

Wash the dishes. With cold water. With hot water. With hot soapy water. With cold soapy water. Keep your eyes open --- there's chemistry going on all around you.

 

What is your knowledge on chemistry, and above all, on experimental chemistry? I know a few, but it depends on your knowledge levels that you could perform them safely or not.

The first one that comes to my mind is exploring the Pourbaix diagram of Aluminum

But it is not something that someone who never did chemistry can do on his own at home, you need basic safety measures.

 

There is lots of interesting things that can be done with cooking and chemistry. Vinegar (acetic acid) and baking soda (sodium hydrogen carbonate) are always fun to mix together. "Bystander" is right, though, there is chemistry everywhere. Keep your eyes (and other senses) "open" as you do your experiments and make your observations. E.g. when you mix vinegar and bakind soda together, what happens to the temperature? What does this tell you?

If you add cream of tartar to egg whites, you get better meringue. Why? If you make meringue in a copper bowl, you get stiffer "peaks;" why? If you knead bread dough it gets more rubbery; why?

 

I refreshed my water chemistry skills by carefully maintaining my hot tub chemistry for its first five years, including Taylor brand colorimetric analyses.
