seperation of citric and phospharic acids
« on: November 12, 2007, 04:12:19 AM »
Hi everyone!
I'm trying to separate the two acids above.
The problem is that both have nearly the same pKa/
Does anyone know if there is a complex that the citric acid will form while the other one won't?
if so, what is the reaction and what are the conditions (pH, temperature, etc...)
Thanks a lot!

Why don't you precipitate one?
