Spot Reaction Experiments
While searching the J. Chem. Ed. on some topic (unrelated to this subject), I came across series of papers published during 1943 to 1945 by Fritz
Feigl.
The "Spot Reaction Experiment" are used for the purposes of identification and detection in qualitative inorganic and organic analysis, in mineralogy,
petrography, biological studies, spot colorimetry and also in analysis of industrial raw materials and technical products.
The Spot Reaction also provides a valuable teaching aid for a variety of chemical facts and principles.
While I do not have active interest in this topic, I thing several SM members are active in this field. This could be of some interest to them.
The series is of 11 papers which are listed in this search.
http://pubs.acs.org/action/doSearch?text1=spot+reaction+expe...
It is not difficult to get any of these papers. Just post requests in Wanted Ref. thread.

Feigl's books are well known and made it through several editions until his death. I'd post old libgen links for the inorganic (1972) and organic
(1966) spot tests but they aren't working, like both the .org and .in sites now.

Do you mean these two?
Spot Tests in Inorganic Analysis

Spot Tests in Organic Analysis

They look very useful, particularly for anyone involved in home chemistry.
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

Downloaded the first one, looks very useful.
Can't get the second one to work. Grrr. Try again later, I guess....

I have been thinking about starting a thread specifically for microchemical reactions and spot tests for some time and got as far as writing my post
as a Word document first because its easier to check and edit this way. I have both of the texts above and can post them but they are large >10MB
files (can someone explain how you link say this page to my yandex public folder?). I have also found several other really interesting books that are
much less well known such as a USBM publication on the identification of opaque minerals by microchemistry.
I got interested through my interest in minerals and this dragged me into chemistry as I tried to acquire/prepare the various reagents.
If you are interested in organic microchemistry check out solo´s link in the reference section and also Wikipedia pages for specific, mostly drug
testing related, reagents.
There is also a really nice German web site for inorganic microscopic microchemical tests with wonderful micro-photographs. I don´t have the web
address but search for "Atlas der mikrochemischen Nachweise der Elemente" by Dr G Rosenfeldt in google and it comes up. There are three volumes.

Libgen is back up...wasn't sure if it was coming back or...
organic: http://libgen.org/book/index.php?md5=90bc2d435c82e8311539829...
inorganic: http://libgen.org/book/index.php?md5=827b06a0199dd0cea9a1cd8...
IDK why the inorganic is 81.5 MB...acrobat 9 pro compresses it (JBIG2 lossy IIRC) to 12.6 MB and it looks fine.
