>Just a little hint. After you've added all the ingredients to make the
exotic FO, if the solution is not a clear clean color, and is dirty or
muddy in appearance, keep adding some oxalic acid until it clears up to a
bright color. The smallest excess of the carbonate can cause muddiness. I
think carbonates can have some excess moisture or be a drier than the last
batch and cause your weighing to be off a little. It's like cake flour, you
have to adjust for the moisture.Dick<
Still another hint I picked up from Dana Sullivan for mixing the exotic
ferric oxalates: a tiny amount, literally a pinch, of EDTA helps the
ingredients go into solution much more easily.---Carl
