Hi All
Sorry for non CCP4 question. I want to make Pottasium Nitrate solution
of pH 6.9 (ofcourse for crystallisation trails only). I'm adjusting pH
by using NaOH. But it seems the pH is not stable after sometime. Is
there any good way to do it.
Thank you
Sajid

to know how.
I would think a solution potassium nitrate in deionized water would have
a negligible effect on the pH of a buffered crystallization solution. I
wouldn't bother trying to adjust the pH, because the solution is not
sufficiently buffered, and depending on the ionic strength of the
solution, may not have sufficient conductivity to allow a pH electrode
to work properly.
Cheers,
