What reading level is The Determination of Nicotin in Nicotin Solutions And Tobacco Extracts book?
To quickly assess the difficulty of the text, read a short excerpt:
Silicotungstic acid does not form such insoluble precipitates with all alkaloids, as indicated by recent work of Javillier. 1 Conin, for example, which is of interest in this connection for the reason that, like nicotin, it is volatile with steam, yields no precipitate with sili- cotungstic acid at dilutions greater than 1 in 5, 000.
1 Javillier, M. Sur les silicotungstates de conlclne, de sparte'lne et d'atropine. Bulletin des Sciences Pharmacologiques, tome 17, No. 6, pp. 315-320, June, 1910....
12 DETERMINATION OF NICOTIN IN TOBACCO EXTRACTS.
In the case of some alkaloidal reagents, such as picric acid, a con- siderable quantity of the reagent must be present before any reaction is evident. Such appears not to be true of silicotungstic acid, for the present writer found that a 1 in 10, 000 solution in one-tenth per cent hydrochloric acid yields an immediate opalescence upon the addition of one drop of a two-tenths per cent nicotin solution, increased to a heavy turbidity upon the addition of more nicotin.
