I've never understood the "super saturated" thing. I use Cu(CuSo4) reference cells for work, and the CuSo4 we put into the halfcell needs to be super saturated. But really, how saturated can something get? You can only put in so much before it doesn't get dissolved by the water.

In the example you used, the CuSO4 is a ligand to the Cu. That's not an ionic or covalent type bonding. It's a complex ion most of the time. The CuSO4 groups around the Cu as much as possible.
In terms of a saturated solution you can alter it through thermodynamic changes. If you increase the energy to the system the solute will dissolve more as most solutions will become more soluble as heat increases. If you had it under an activation energy graph you could see the amplitude and relate that to how much of the solute is in solution.
This followed by rapid cooling to put it in a thermodynamic hole where the energy decrease is faster than it can precipitate out the system can have the same dissolved material at 25°c.

I'm glad that chemistguide.org is interested in having a robust discussion about how best to clean my bong.

I bought my inner child a Christmas present today. Star Wars battlefront ps4. Staying home tomorrow!

Today was one of those days when everything falls into place for a good late fall riding session, weather, afternoon off from work, bike in tip top shape and yet I couldn't ride nice and loose like I did last week when the weather was shit.
blueee:
it's either ride my bike or read books
