And here I was happy to learn something new on social media contradicting my previous knowledge lol. But yeah, I definitely intend on having a basic chemistry refresher video now!
Comment on Sweet tea
Nommer@lemmy.world 11 months agoYes. Not sure what the other person is on about. Hot water can have more sugar dissolved in it. When it cools it crystalizes. It’s how rock candy is made. This is like basic chemistry.

Hot water dissolves it much quicker, giving the illusion that it dissolved more. It’s not actually saturated when you’re trying to stir it into cold tea, it just dissolves extremely slowly. If you were to saturate it while hot (which would take an insane amount of sugar), then yes, it would recrystalise. But in pracrice, you need to dissolve it while hot because the more energetic molecular motion in the solution dissolves the sugar faster, since the heat is causing more effective collisions. Saturation point and the change thereof is, contrary to the proposal above, not a factor here, since everything is happening well below that point even with the sweetest teas commercially available.

It’s not about achieving saturation, it’s about how quickly it dissolves. The sugar packets would absolutely dissolve, if you stir vigorously for half an hour… Rate of dissolving varies as temperature. 9th grade chemistry…

That wasn’t the original argument now was it? If you’re going to move goalposts then at least be halfway correct the first time.
