When converting an acid salt dissolved in water to its acid form, you are instructed to adjust the ph well into the acidic range (ph = ~2). why don’t you just take the ph to neutral? you do the same for adjusting the ph of a solution containing an amine salt taking it well into the basic range rather than neutral. why are you instructed to do this?

The answer lays in logD.

Explanation:

So when you end up with neutral pH  amine or either carboxylic acid can still be in a salt form. So for every compound the pH level of unionized form is different and for the best extraction experience is better to perform and extraction at as low as possible pH for acids and for amines as high as possible.

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.
