novel STB tek idea

[dread]

Well... aren't there easier ways to dry-basify mhrb?

I seem to remember hearing of such, can't remember the details atm though. Could probably find it in the nexus...

And o-Dichlorobenzene has a dipole moment of 2.14, but I can assure you it will never dissolve any amount of KOH. Yeah, polarity of molecules can help you make some predictions, but solvation is actually pretty complex and depends upon a lot more than just knowing the polarity of your solvent.

I predict that no or virtually none of the KOH will dissolve in the difluoroethane, but if you have access to them you can do a quick experiment. Put some KOH on some filter paper in a funnel. Pour a fixed volume of difluoroethane over the KOH and let it pass into a beaker. After the difluoroethane evaporates, mass how much KOH is in the beaker.

I will do that this weekend,
and dread if you find that process, please share it

edit: The dipole moment of 1,1 difluoroethane is 3.69 D, compared to 1.85 for water
its definitely polar

Believe it or not, dipole moments are different for liquids than for gases. 1,1-difluoroethane gas has a dipole moment of 2.27. It's definitely polar though; I have no idea how anyone can argue that its non-polar I mean just look at it.

I'm pretty sure that duster won't dissolve solid lye. Bright side is it has a critical pressure of like 41 atmospheres so on the surface of Jupiter it'll always be a superliquid

dielectric constant isnt a measure of polarity, the dipole moment is

i'm still searching for it.

but knowing how electronegative fluorine is, especially compared to carbon, and the fact that both fluorines are on the same carbon, there is bound to be a significant dipole moment

Here is the quote directly from Wikipedia: "Generally, the dielectric constant of the solvent provides a rough measure of a solvent's polarity. The strong polarity of water is indicated, at 20 °C, by a dielectric constant of 80.10. Solvents with a dielectric constant of less than 15 are generally considered to be nonpolar." Since 1,1-difluoroethane has a dielectric constant of 4.67, according to Wikipedia, it is nonpolar.

your reply seems to come from someone with little to no understanding of the word polar. If you do, I am sorry to offend. But simply looking at the molecule is enough to discern that it is polar, not to mention the diPOLE moment in gas and liquid phase, and seep's agreement (i think she knows more than either of us).
