Greetings all,
I seek some helpful information from a someone with a more recent and
formal chemistry education... mine is becoming rather "long in the tooth".
A friend has cleaned out his darkroom and I am given two brown glass jars
containing about three to five hundred grams of chemicals.... neither of
which is now labelled.
I am assured that one contains potassium ferricyanide and the other either
potassium or sodium dichromate.
The contents of the two jars seem quite similar in "texture" and colour.
Since I believe I can make use of the contents once identified, does anyone
know know of a ready and simple way to identify which might be which?
Ken
