I can't seem to find a list of polar liquids...

I think HydroChloric whatever is a polar molecule.  H-Cl

The trick is to find a polar liquid that would likely be formed in large amounts under specific conditions (say, a planet's formation).  That narrows the list considerably.

thats a one aswell. those who contain hydrogen is likly to form. and nitrogen should be more than oxygen cause its lighter, but hydrogenflouride is better than chlordide but it should be less of it.

The trouble with Hydrogen Fluoride (HF) is that is is highly reactive. It would utterly destroy a cell membane in seconds.

on a planet where FH is liquid dont you think life would adept its chemicals to not react with it if it didnt "want" it to happen? anyhow I found a list of how polar the molecules are:
HF 1,91
HCl 1,05
HBr 0,8
HI0,42
H2O 1,84
H2O2 2,12
NH3 1,48
SO2 1,63
NO 0,16
NO2 0,4
CO 0,1
CH3OH 1,7
this is in debyes

Trouble is that HF reacts with EVERYTHING

I use it to convert samples of organic tissue, rock, glass, quartz, whatever into liquid form for chemical analysis.

About the only thing it doesn't destroy is Zircon crystals

If you can come up with a way that life could evolve inside a solid zircon crystal then maybe it could work but again the trouble is that although these crystals could initially form as insoluble Zirconium Fluoride, no other chemicals in the chemical soup would be able to leave solution in order to form any viable molecules.

well then its a problem. Why is it so reactive?

HF in solution (possibly 100% since it is a liquid at normal <19C temperatures) is technically defined as a weak acid.
This definition does not mean what you might think though. A weak acid is one which ionically dissociated in an aqueous medium. HCl and HBr are other weak acids while things like Nitric acid (HNO3) and Sulphuric acid (H2SO4) are considered strong acids.

What make HF so corrosive is not its acidity but is actually the fact that the F- anion is the most electronegative thing known to science. (electronegativity relates to its afinity for electrons) In this state the Fluorine atom has an extra electron which it desperately wants to lose to form a bond with another atom.

Usually F- will prefer to make an ionic bond (salt) with H+ or another electropositive element like Sodium or Potassium but hese bonds are (unfortunately for life forms) transitory. They exist as an equilibrium HF <--> H+ + F-
This means that until the F- anion finds a permanent home in a covalent bond, it just keeps moving around displacing other bonds. Basically it is a wrecking ball that breaks up other molecules. Once it does find a permanent home (usually attached to a carbon atom in place of some useful bond that used to be there or in a very strong ionic bond with one of the rare earth elements) it increases the concentration of free protons in the solution because H+ and F- are no longer in equilibrium.
So as Fluorine is used up, the acidity of the solution also goes up (pH goes down). Now the protons move in and begin reacting with the broken molecules.

The overall result of any object in HF is that you end up with a solution of metallic fluorides and all the Carbon originally present in the object converts to CO2 gas

HF facts

HF is the only solvent known to directly attack glass.

An HF burn on your skin only needs to to be over a 10 square cm area to be fatal.

HF can kill without any visible burn at all on the skin.

F- anions preferentially attack metals. They are able to travel though intact skin and will strip the Calcium from your bones. The H+ is the part that will destroy tissue.

HF gas (>19C) is the most corrosive gas known to science.

Don't mess with HF unless you are highly trained to do so.

Nahh! I shouldn't bother. Your foot is going to drop off either way. It could also be too late to save your life already so you should just do your best to ignore the excruciating agony and work on DarwinBots while you still have the time.  :D

But if you do decide to, please note that at the bottom of the forum you will now find a direct link to image shack so that you can upload your own piccies to their free hosting site then copy the link over to your post. Makes for very fast loading of pictures.   :D  :D  :D

PY, its a nice little HTML, but you included it sloppy, the "host it" button ends up being cut of by the invison "hosted by" thingy.

I didn't write the HTML so don't blame me for the sloppy button. :(
The button looks exactly the same their own site. We are just linking into it. I haven't modified anything in the code.

It looks absolutely perfect in Mozilla firefox anyway.  :P

sure does.

ah good ... another firefoxer ;)
take back the web!!!
I imagine you have played at reconfiguring yours a bit ...
seems like there's a lot one can do.
I haven't done much but add an extension or two ...
but I certainly do like it.
