[edit] HI solubility in water
Under 'Properties of hydrogen iodide' it says: "One liter of water will dissolve 425 liters of HI [...]" Isn't it a bit unclear what is meant here (bear in mind I'm no chemist)? Is it 425 liters of (gaseous) HI at 20 degrees celsius? Gaseous HI has, I presume, a fairly low density which would mean 425 liters of HI isn't very much.
[edit] Comment from article
I leave it to others to outline the chemical formula for this reaction.

- It seems to me this article falls into a 1st year chemistry trap: at one point it seems to overlook the fact that when an acid is dissolved into ions, it does not protonate. The proton simply does not exist freely in solution. Instead, we observe the hydronium ion (H3O+) and the equation must include water for it to be a balanced equation as a result. I'll alter it and leave you all to pick at it :) Mattabat 22:06, 3 February 2007 (UTC)
- Those equations, as fixed up, look a little mangled in Internet Explorer! - I'm going to leave them however as they are correct (and look good in Firefox). Guess Internet Explorer needs work.. Mattabat
[edit] Dissociation energy of HI
Silberberg's Chemistry, 4th edition, lists the bond energy of HI as 295 kJ/mol, which means a photon of wavelength ~406nm will cause a molecule to break. Where was 578nm obtained from in this article? Also - why does wikipedia distinguish betwen dissociation energy and bond energy? No text I can find distinguishes them, and several specifically state they are the same. 169.233.62.35 18:55, 14 July 2006 (UTC)
