RE: potassium vs. ammonium citrate pd developer

Anyone who's capable of mixing a couple of compounds without being
provided information on proper working procedures, solution strenghts,
necessary materials / supplies / equipment and safety precautions, and
doing this by disregarding any warning - such as the one in my message
-, is perfectly capable of harming him/herself and others without my /
your / our help, even without "playing" with chemicals (I mean in much
more creative ways). Be assured...
 
The question about citrates -> that should be asked to those who use
them (I don't use developers for pt/pd - I work with a POP process).
FWIW, it's said that Ammonium Citrate gives more neutral color.

It is a reasonable assumption that you know.

The danger is that students of whatever age assume that because they
see 'teacher' just mixing a coiuple of things together, it can work just
as well with other chemicals.

I suppose the danger can be increased when the 'experts' are on line and
not in the studio or lab to supervise.

Incidentally, what do these citrates do that potassium oxalate does not
?
