What does this mean?[edit]

The page says "Conversely, the addition of a base to a mixture of an organic acid and base will result in the base remaining uncharged, while the acid is deprotonated to give the corresponding salt. Once again, the self-ionization of a strong base is suppressed by the added base."

I can understand that it is the usual acid and base reaction and the products are a salt and water but the above text is unclear and doesn't mention water at all. Also, "Once again, the self-ionization of a strong base is suppressed by the added base" seems to be wrong. Vmelkon (talk) 13:48, 22 December 2011 (UTC)

A picture is worth a 1000 words[edit]

I think an illustrative diagram/scheme near the start of this article would help the readability of the article.


I think this diagram/scheme can take the form of a series of steps where the amine "moves" from an organic phase into an aqueous phase, and then back to the organic phase as the pH of the solution is adjusted.


Included in this diagram/scheme could be the terms "organic soluble impurity" and "aqueous soluble impurity". At each stage of the diagram/scheme it can be shown that these impurities are be removed, thus giving the amine free of impurities. I don't think this diagram/scheme should be too had to make, it only requires a little imagination ... and as always some time.


It would be nice to hear any reasoned opinions for or against this idea here. -- Quantockgoblin 00:28, 19 March 2007 (UTC)

I am stuggling to understand the theory and technique of the process. In 'Technique' it says that the pH of the aqueous acid/organic solvent solution is adjust to bring the substance to its required form. Please elaborate! —Preceding unsigned comment added by 71.125.24.195 (talk) 17:08, 7 March 2008 (UTC)
