[phenixbb] preparing DL-Malic acid stock solution

[Sebastiano Pasqualato]

Dear all,
we’ve recently having trouble preparing a 3 M stock solution of DL-Malic Acid, pH 7 (which we had, so it’s doable!).
When we reach pH 3 - 4 the solution turns milky white and does not goes back to a clear solution even when the pH is raised.
Does anybody have any advice on how to get a clear solution? Has anyone gone through the same?
Thanks in advance,
ciao,
Sebastiano
