Solution of ammonium sulfhydrate is added to the precipitate on the filter, which is then washed with water. The solution passing through may contain As, Sb, Sn and Cu the residue on... [Pg.136]

Chromic Salts.—(l.) Potash, green ppt. an excess of precipitant forms a green solution, from which CraOa separates on boiling. (3.) Ammonium hydroxid, greenish-gray ppt. (3.) Ammonium sulfhydrate, greenish ppt. [Pg.150]

Analytical Characters.—Manganous.—(1.) Potash, white ppt., turning brown. (2.) Alkaline carbonates, white ppts. (3.)

(5.) Potassium cyanid, rose-colored ppt., forming brown solution with excess. [Pg.151]

Analytical Characters.—Fbrbous—Are acid colorless when anhydrous pale green when hydrated oxidized by air to basic ferric compounds. (1.) Potash greenish-white ppt. insoluble in excess changing to green or brown in air. (2.) Ammonium hy-droxid greenish ppt. soluble in excess not formed in presence of ammoniacal salts. (3.) Ammonium sulfhydrate black ppt. insoluble in excess soluble in acids. (4.) Potassium ferrocyanid in absence of ferric salts) white ppt. turning blue in air. (5.)

In the analysis for mineral poisons (see p. 136), the major part of the Pb is precipitated as PbS in the treatment by HjS. The PbS remains upon the filter after extraction with ammonium sulfhydrate. It is treated with-warm HCl, which decolorizes it by transforming the sulfid into chlorid. The PbClj thus formed is dissolved in hot H 0, from which it crystallizes on cooling. The solution still contains PbCh in sufficient quantity to respond to the tests for the metaL... [Pg.168]

Analytical Characters.—(1.) Its intensely bitter taste. (3.) Its alcoholic solution, when shaken with a potassium salt, gives a yellow, crystalline ppt. (3.) An ammoniacal solution of cupric sulfate gives a green, crystalline ppt. (4.) Glucose, heated with a dilute alkaline solution of picric acid, communicates to it a blood-red color. (5.) Warmed with an alkaline solution of potassium cyanid, an intense red color is produced (the same effect is produced by ammonium sulfhydrate). (6.) Unbleached wool, immersed in boiling solution of picric acid, is dyed yellow. [Pg.407]

If sodium sulfhydrate, equal to basicity of pH 10-11, is used in hydrolysis, 93 % A -ester group of nitrate esters is hydrolyzed to nitrous acid ions and 7 % is hydrolyzed to ammonium. If ammonium sulfhydrate is used, the concentration of nitrous acid ions will be increased to a maximum first and then decreased to zero because of the reduction of ammonium sulfhydrate. The reduction effect would be increased with increasing pH value, especially at pH over 10. The reaction can be expressed as following chemical equations. [Pg.188]
