To introduce students to the tests, and to provide hands on experience in
determining whether these tests apply to the fluids involved.
(For a Class of 14 Students.)
Chemicals are an amino acid, glycine, for the first test (chromatography),
Benedicts solution to test for excess glucose (glucose needed), and iron
chloride to test for salicyclic acid which are also needed.
8 strips of Whatman No. 4 chromatography paper about 20 cm long
Twenty-five 25 x 200 mm test tubes
5 test tubes
