Notes: Water in motion will pick up charge from the air or from what it is in contact with. Therefore for water to be neutral, it must be at rest and at equilibrium. I'm not sure whether there is any difference if liquid water is exposed to SATP (100% RH) or not. I'd guess we probably can't measure the difference.
Significant deviations from the assumption stated in the article often occur in real world conditions. If I recall, in a 10% solution of NaOH the assumptions are not so good. Anyways, you can easily get to pH numbers (measuring the H/sup/+ concentration) well below zero, and to numbers above +14. ( with the fugacity diverging from that calculated from ion concentrations). Since now-a-days, Molarity isn't a good indication of a solution's "strength" (polymeric solutions have low Molarity), it should be stated that the assumptions are accurate in "dilute" aqueous solutions. Of course, the definition of dilute often rests on the accuracy of similar assumptions and makes the logic circular.
Vapor phase equilibria are not the same as for liquid water. Ion populations and H-bonding differ so that the numbers are different too. -DEN 6-17-2005
[edit] Auto?
I thought it is more common to refer to this as autoionisation. As opposed to self-. Google hits are pretty close, and "self-" has the benefit of a hundred Wikipedia forks/copycats... -- Миборовский U|T|C|M|E|Chugoku Banzai! 02:05, 27 February 2006 (UTC)
- Actually, "autoionis/zation" gets 200,000 hits while "self-ionis/zation" gets 16,000. -- Миборовский U|T|C|M|E|Chugoku Banzai! 02:06, 27 February 2006 (UTC)
I thought autoionization was more common also, but when I looked, "self ionization water" gets 473,000 Google hits compared to 131,000 for "auto ionization water". (The s for z variant is a small fraction of usage, and separating the words instead of using the hyphen includes both types in the search results.) So the present title seems OK for now. --Blainster 21:27, 28 February 2006 (UTC)
[edit] Omitting [H2O(l)]^2
Do we actually omit it ... I thought it was still there since the activity of pure water we take as unit. Is this correct? —Preceding unsigned comment added by 129.11.197.210 (talk • contribs)
- Yes, you are right, but taking the activity as 1 equates to the same result. -postglock 12:34, 13 December 2006 (UTC)
[edit] Math-ize (LaTeX) the equations?
Since the maths equations TeX parser should give HTML for relatively simple equations, it could be easier (and cleaner) to just write the equations in TeX. Any objections? -Matt 15:39, 16 June 2007 (UTC)
