What reading level is A Manual of Chemical Analysis Qualitative And Quantitative book?
To quickly assess the difficulty of the text, read a short excerpt:
By the method on p. 49.
If phosphoric acid is present, \hz precipitate is treated as explained on p. 68. The filtrate is then saturated with sulphuretted hydro- gen, ! gently warmed, and filtered. The precipitate is examined for the metals of Group 1 1 IB. According to the plan on p. 62.
(4) Separation of Group IV. The filtrate from Group 1 1 IB. Is boiled briskly, with the addition of a little hydrochloric acid, to decompose ammonium sulphide and expel all the sulphuretted hydrogen. Any precip...itated sulphur is removed by filtration. The solution is then rendered alkaline by addition of ammonia, and ammonium carbonate added until precipitation is complete. The solution may be warmed, but must not be boiled (see p. 34). The precipitate is examined for the metals of Group IV. , as indicated on p. 35. \ (5) Detection of Metals of Group V. The filtrate from Group IV. Is tested for magnesium, potassium, and sodium, J as described Jon p!\25.
is likely to render certain oxides (e. G. Fe 2 O 3, Cr 2 O 3, A1 2 O 3 ) very difficult of solution in hydrochloric acid** * If by a preliminary test upon a small portion of the solution (by evapo- rating it upon a platinurtf capsule) it is found that there is no silicious or carbonaceous residue, the mail bulk of the liquid need not be evaporated down.
