Amazing chemistry at work!

[speedy_thrills]

Hey all, I need some wise PH advice. Just saw a sign down at Subway (On Jackson street, Petone, Lower Hutt, Wellington, New Zealand for those of you playing at home) that one of the workers had put on the coffee machine saying “Oxygen hydride” evidently put up by an overzealous worker who did not pay attention in chemistry class, now I didn’t think that such a molecule existed and it turns out it does (after a quick google) but only on one website: www.evidencesofcreation.com/atom06.htm Mind you the same website also follows with a passage from (As far as I can ascertain) the Koran .

Any way I was wondering what my course of action should be? Should I go down and as to buy their entire supply of Oxygen hydride as fast as possible? Should I be aware of any radioactive decay? Is their the possibility that they will try to sell me much inferior Aqua, Water, Dihydrogen monoxide, Hydrogen Hydroxide or Oxygen dihydride? How can I tell the difference so I don’t get scammed?

I’m sure you can see why I need help on this fine issue.

actually no such thing...

hydrogen atoms in molecules can be protic or hydridic. The hydrogens in water are protic - water can be deprotonated to gie HO- (hydroxide) and H+ (a proton). Hydrogens in molecules lik ethanol, ethanoic acid (acetic acid), sulphuric acid etc. all behave like this.

hydridic hydrogens are much more interesting compounds like LiHBEt3 (lithium triethylborohydride) and NaBH4 (sodium borohydride) are a source of hydride, H-, and are really usefull for reducing things. they're great.

no more geekiness now

Why would the people at Subway lie to us?

Intelligent discussion! This forum has plenty of it (mainly not contributed by me ).

I think the IUPAC name is "Oxane" now, which is a bit silly if you ask me. I wonder what overpaid think tank came up with that.

Damn.. thought this was another Dating thread!

I hope you're joking

I still think they are daft for making the official name of Al Aluminum, as whenever I hear someone say 'Aluminum', all I can think of is Dr Denzil Dexter, no metter how important or serious the discussion

But, after buggering about with nomenclature, we still buy bottles of toluene, aniline and red iron oxide. Try making industry deal in anything other than the old names. As long as everyone knows what everyone else is on about eh? People renaming inorganic compounds are just wasting time, money, ink and should be shot.

As for bloody Aluminum, I well hope you are joking. About 99% of chemistry subject matter comes from the UK, how dare the yanks bastardise our subject with their bastardised version of our language

I wish I was joking, but alas it is true. (Especially the Dr Denzil Dexter part)

It's not Oxygen Hydride. It's Dihydrogen Monoxide!

Didn’t this joke come from some guys in a California town who managed to get it banned from the township?

OK, so here's a question: Does completely pure water self-ionize and expedite reactions with metals, as compared to dilute solutions that are nearly all water? I know someone who uses distilled water with his equipment, but insists that de-ionized water causes it to rust faster than with distilled (which can have very small percentages of Cl, etc.) I can only imagine that if the pure water self ionizes, corrosion takes place more easily, where as in a dilute solution, the solvation shell around one ion creates a situation where the water molecules hold a particular orientation as molecules and do not actively self ionize. But then, the solution would have to be very weak. An electrolytic solution speeds corrosion even further.

Water is always in equilibrium with itself thusly:

2H2O <--> H3O+ and -OH

but don't think the equilibrium constant is very big for that.

De ionised and distilled water absorb CO2 from the atmosphere too which of course makes carbonic acid in solution. If we get freshly distilled water and leave it in our lab for a couple of weeks it ends up being about pH 5. Some of this is probably due to the slightly acidic atmosphere in the lab (metal corrodes over time just by being in the lab!) but some of it will be from dissolution of carbon dioxide in the water.

I can't really remember the rusting reactions but as far as I do remember them I think you need Cl- and water? I'm not sure if other anions can take the place of the chloride.

might look it up and find out
