What reading level is Forensic Chemistry Electronic book?
To quickly assess the difficulty of the text, read a short excerpt:
The same colours are produced by codeine, dionine and heroine. Other tests for morphine are as follows : — (1) A drop of Frohde's reagent (0-1 gram ammonium molybdate dissolved in 10 c. C. Of cold strong sul- phuric acid), which must be freshly prepared, gives with morphine a violet colour changing to blue and finally to dirty green.
(2) Strong nitric acid gives an orange-red colour changing to yellow.
(3) Pellagri's Test. Dissolve the solid morphine residue in two drops of strong hydrochloric ...acid to which a small drop of strong sulphuric acid has been added. Heat on the water bath for half an hour, a pink to brown colour being i)roduced. Cool, dilute with water, and add a few droits of sodium bicar- bonate solution until alkaline. The colour changes to red. Add a small drop of an alcoholic solution of iodine, when an emerald-green colour slowly develops. Excess of iodine spoils the test. If a little ether is poured on the surface of the liquid, the ether takes a reddish tinge, the water solution remaining green.
