If you were given water and hydrogen peroxide, how would you find the difference between them? (They have the same ph, are odorless, and look pretty much exactly alike, just as a reminder)

Put some iodine in them. The hydrogen peroxide will fizz right away, but the water will have no reaction.

New Question: What is the only way to tell apart salt and sugar?

The shape of the granules, and the taste. Salt is mainly cubic, and sugar looks a bit like a fallen column. Of course sugar is sweet, and salt is, well, salty.

Correct! Your turn. (I don't think we're allowed to taste it)

What’s are the differences between wool and silk (when burned)? (Hey girls you doing the curiosity confidence challenge?)

I think wool has a stronger odor than that of silk, although they are similar. Also, silk stops burning once you take it out of the flame but wool may continue for a bit.

How do you identify the difference between polyester, nylon, and acrylic in a burn test? How do they differ underneath a microscope?
