Actually stating the law in written English...[edit]

For some users, the following may create a greater ammount of understanding/clarity, in addition to just having a formula.

For any weak electrolyte, Ostwald's dilution law states that the degree of dissociation is inversely proportional to square root of the molar concentration and is directly proportional to the square root of the volume containing one mole of electrolyte.

I don't know if that is correct, but it may be easier for some to digest. Emesee (talk) 19:02, 25 August 2008 (UTC)[reply]

Link to activity coefficients for the case of strong electrolytes[edit]

I think the article should present also the situation for non-weak electrolytes solutions where activity coefficients are required.--5.2.200.163 (talk) 13:50, 15 June 2018 (UTC)[reply]

I agree that a section on stronger electrolytes would be useful. However it is not entirely obvious which equations are valid: the equilibrium constant probably should involve activities rather than concentrations, while conductivity could be described by the Debye–Hückel-Onsager equation. Best would be to find a good reference, perhaps a book on electrochemistry. Dirac66 (talk) 01:43, 17 June 2018 (UTC)[reply]

It is interesting to notice that conductivity as a transport property is approached by DH(O), which was primarily intended for equilibrium properties like activity.--5.2.200.163 (talk) 15:47, 28 June 2018 (UTC)[reply]

I have now rewritten the section and clarified the situation for weak electrolytes as well as strong. Dirac66 (talk) 00:32, 26 June 2018 (UTC)[reply]

An interesting source in electrochemistry which may contain some aspects of interest here by Paul Delahay, mentioned in a review [1] , including perhaps an expression containing the lambda factor for conductivity (electrolytic)--5.2.200.163 (talk) 16:04, 28 June 2018 (UTC)[reply]

Essentially complete ionic dissociation of strong electrolytes and high concentrations[edit]

I think that the assumed essentially complete ionic dissociation of strong electrolytes requires a specification of the concentration domain where it holds and the threshold where it starts not to hold.--5.2.200.163 (talk) 13:48, 3 July 2018 (UTC)[reply]

Mixed solvents systems[edit]

I think it would be interesting to see what expression this law has in mixed solvents systems and what are the dissociation equations.--5.2.200.163 (talk) 13:51, 27 July 2018 (UTC)[reply]
