Incorrect unit for A[edit]

The unit for A is said to be kg^1/2 * mol^-1/2 but a simple unit analysis will show that it is incompatible with the equation given (which yields m * mol^-1/2). The reference is for the 1998 book of Hamann and Hamnett which I do not own, however the second edition from 2007 does not give this equation explicitly. — Preceding unsigned comment added by Bjodah (talkcontribs) 17:07, 24 April 2015 (UTC)[reply]

Deviations from Raoult's Law[edit]

Can someone provide information on how activity coefficients demonstrate either positive or negative deviations from Raoult's Law? 171.64.133.56 22:52, 24 February 2006 (UTC)[reply]

variables in Debye length[edit]

Hi 152.1.193.141, thanks for your edits in this article but what do the variables mean in the new section on Debye length? Could you include an explanation in the article? V8rik 20:56, 6 November 2006 (UTC)[reply]

Link to the book I used that contains the English translation of the Debye papers on Amazon[edit]

Note for others on wiki links[edit]

I have sometimes duplicated wiki links to other articles inside the theory section because I believe it is becoming large enough to warrant its own article and I don't want to have to go through to determine what links need to be made again. —Preceding unsigned comment added by ChrisChiasson (talkcontribs) 11:05, 4 October 2007 (UTC)[reply]

Not a course[edit]

Hi all. I've seen the parts of the article, and it looks too much like an academic course. Brr, scary.46.193.167.226 (talk) 14:11, 9 December 2013 (UTC) BST[reply]

Debye-hückel limitting law equation[edit]

I have two questions concerning the expanded form of the debye-huckel limitting law. First of all, would it not be better to specify that "log" refers to the natural logarithm (ln) and not the base-10 logarithm. Also, the denominator used (8*pi*relativepermitivity*permitivityoffreespace*k_b*T) is itself an approximation. More formally, one would add the term (1+kapa*a_0), where kapa is the Debye screening length and a_o is the ionic-radius. Wouldn't it be better mention the fact that we approximate this term to equal unity? -- Billjoie (talk) 14:30, 27 November 2008 (UTC)[reply]

Assessment comment[edit]

The comment(s) below were originally left at Talk:Debye–Hückel equation/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.

I would suggest that the page be re-written to separate the contents of the historical paper from the derivation. An explanation of the Debye-Hueckel/Kirkwood charging process is missing, and that section of the derivation (the evaluation of integration constants) could be done more clearly, with a particular focus on the activity coefficient.

Also, the Debye-Hueckel model does not conform to a Helmholtz model of the double-layer, rather a Gouy-Chapman model. I will make that edit myself.
