Preparation and purification of potassium organic carboxylate
You can first test the pH of the potassium salt solution you get, and then calculate the solution theory PH by the carboxylic acid KA or PKA you use, if it is close to it.Potassium carboxylate solution pH is generally around 8-9. Recrystallization of carboxylic acid: It can be tested first with water, then adding low-temperature freezed absolute ethanol or acetone, which is crystallized under low temperature stirring.

is a potassium hydroxide
in the carboxylate salt of the carboxylate
, the calci-base titration method can be accurately gram / liter
and thereby guides hydroxide.If the potassium is added
If there is more potassium, it can be adjusted according to the analysis value, and the carboxylic acid regulation
