Antimonyl potassium tartrate,

Potassium Antimonyl Tartrate (Tartar Emetic). C4H40 KSb0,... 

Tartaric acid is noteworthy for a) the excellent way in which the majority of its salts Crystallise, and h) the frequent occurrence of salts having mixed cations. Examples of the latter are sodium potassium tartrate (or Rochelle salt), C4H40 NaK, used for the preparation of Fehling s solution (p. 525), sodium ammonium tartrate, C4H OaNaNH4, used by Pasteur for his early optical resolution experiments, and potassium antimonyl tartrate (or Tartar Emetic), C4H404K(Sb0). The latter is prepared by boiling a solution of potassium hydrogen tartrate (or cream of tartar ) with antimony trioxide,... 

Add 5 g. of potassium hydrogen tartrate and 5 g. of antimony trioxide (each being finely powdered) to 30 ml. of water contained in a small flask, and boil the mixture under a reflux water-condenser for 15 minutes. Then filter hot, using a Buchner funnel and flask which have been preheated by the filtration of some boiling distilled water. Pour the clear filtrate into a beaker and allow to cool. Potassium antimonyl tartrate separates as colourless crystals. Filter, drain and dry. Yield, 5 g. The product can be recrystallised from hot water, but this is usually not necessary. 

Reagents. 0.005 M Potassium antimonyl tartrate solution. Dissolve 1.625 g of the solid in 1 L of distilled water. Dilute 25.0 mL of this solution to 250 mL with 1M hydrochloric acid which is 0.05 M in potassium bromide. 

This ammonium phosphomolybdate complex is yellow, but if mildly reduced by ascorbic acid in the presence of potassium antimonyl tartrate a solution of stable bluish-purple color ( molybdenum blue ) develops after about ten minutes, which has its strongest absorption at 882 pm (Fig. 4.6). Other mild reducing agents have also been used, including tin(II) chloride, or hydrazine sulfate, which give maximum absorbances at slightly different wavelengths. The intensity of the color which develops is linearly proportional to the... 

Note In this experiment, the phosphorus in water samples is determined by visible spectrometry following a reaction of the phosphates in the sample with potassium antimonyl tartrate, ammonium molybdate, and ascorbic acid. All glassware should be washed in phosphate-free detergent prior to use to avoid phosphate contamination. 

Potassium antimonyl tartrate solution. In a 250-mL Erlenmeyer flask, dissolve 0.45 g of potassium antimonyl tartrate in about 50 mL of distilled water. Swirl gently until dissolved, and then dilute to 100 mL and swirl to make homogeneous. Prepare just prior to the run. 

In Refs. 3-5, potassium antimonyl tartrate was used as a source of Sb. While the deposition conditions appeared to be almost identical in all cases (other than the silicotungstic acid added in some cases in the latter two studies), there were some unexplained differences in structural and electrical properties (the latter shown in the table). The lower resistivities obtained in the first study were mirrored by higher carrier concentration (2 X 10 cm vs. 10 cm ) and slightly higher mobility (14 vs. 10 cm V sec ). 

The salts of basic tellurium are colourless and are easily hydrolysed in dilute aqueous solution with formation of the dioxide. The addition of tartaric acid checks the separation of the dioxide on account of the formation of the stable acid tellurium tartrate Te(IIC4H406)4,5 which can be obtained in the crystalline condition, as also can the silver telluryl tartrate Aga(Te0)(C4H406)2, analogous to potassium antimonyl tartrate.6... 

Arsenious oxide is insoluble in dilute sulphuric acid but reacts with fuming sulphuric acid to give a series of very unstable crystalline compounds of general formula As203.nS03. These are resolved into arsenious oxide and sulphuric acid on contact with water. The formation of a crystalline arsenyl tartrate, Na(As0)C4H406, analogous to potassium antimonyl tartrate, has been cited as evidence of the basic nature of arsenious oxide, but the product may contain the arsenic in a complex anion. 

By the action of chlorine and chlorine compounds on the sulphides of arsenic. By passing chlorine over the dry sulphides, realgar or orpiment, at 130° to 140° ., theoretical yields of arsenic trichloride and of sulphur dichloride are obtained.5 The trisulphide reacts with hydrogen chloride in the cold, but chlorination by means of hydrochloric acid is difficult, only a small quantity of the chloride being volatilised.7 The reaction is facilitated by the presence of ferric chloride,8 cuprous chloride or potassium antimonyl tartrate.9 Other chlorinating agents, effective with the sulphides, are sulphur mono-chloride,10 a mixture of ammonium chloride and nitrate,11 and mercuric chloride.12... 

Three and four-tenths grams of antimony trisulfide is prepared by passing hydrogen sulfide into a solution of 6.6g potassium antimonyl tartrate (4.5g of the trichloride or 2.9g of the trioxide may be used instead) in 2N hydrochloric acid until precipitation is complete. 

A solution of 0.2g-0/3g of potassium antimonyl tartrate (tartar emetic) in 100ml of water Is treated with hydrogen sulfide for a short time An orange-yellow sol is formed which is dialysed in running water for 2-4 days ... 

Basic dyes of the azo class were among the earliest known synthetic dyes. They were used originally for dyeing cotton mordanted with tannin and potassium antimonyl tartrate and wool from neutral solution. They continue to have minor importance for dyeing leather, paper, plastics, and waxes, and as constituents of graphic arts colors. 

Cupric metantimonite, Cu(SbO2)0.—The metantimonite is obtained in light-green crystals by addition of cupric sulphate to an alkaline solution of antimonious oxide or of potassium antimonyl tartrate.6...

A simple resolution of Ni(phen) 5+ using potassium antimonyl tartrate has been published (415). Also the resolution of the mixed chelate complexes Ni(phen)2(bipy) + and Ni(bipy).) phen) - has been achieved (102). The spectra of these two cations are similar, but that of the bisbipyridyl complex changes rapidly in acid solution (red blue). 

Mordant pieces of test fabric by allowing them to stand in a hot (nearly boiling) solution of 0.1 g of tannic acid in 50 mL of water for 30 min. The tannic acid mordant must now be fixed to the cloth otherwise it would wash out. For this purpose, transfer the cloth to a hot bath made from 20 mg of potassium antimonyl tartrate (tartar emetic) in 20 mL of water. After 5 min, wring the cloth and dry it as much as possible over a warm hot plate. 

Standard antimony solution 1 mg/ml. Dissolve 2.668 g of potassium antimonyl tartrate (Sb0)KC4H40e in HCl (1+1) and dilute the solution to 1 1 with this acid. Working solutions are obtained by suitable dilution of the stock solution with HCl (1 + 1). 

A solution of 20 mg of this complex in 10 mL of water is poured into a column containing Dowex 50W-X8 resin (200-400 mesh, 2.5 cm x 34.5 cm, Na+ form). The adsorbed band is eluted with a 0.3 mole/L potassium antimonyl-( + )-tartrate solution. When the adsorbed band descends to four fifths of the...

Electrolytes which do not afford ionic complexes with common hexitols and reducing sugars are aqueous solutions of lead acetate, copper sulfate, zinc sulfate, ferrous ammonium sulfate, calcium chloride, potassium dichromate, ferric chloride (pH 3), aluminum sulfate, magnesium sulfate, sodium sulfate, potassium antimonyl tartrate, sodium arsenate or arsenic acid, sodium phosphate, and hydrochloric acid. It is not certain whether sodium aluminate (in 0.1 N sodium hydroxide) affords ionic complexes with carbohydrates, as aqueous alkali, alone, permits their migration during electrophoresis.
