Silver chloride nitrite

The nitrite, [Ir(NH3)4(NO2)2]NO2.H20, is easily soluble in water, and on addition of sodium nitrite to a solution of the chloride is only partially formed. It is best prepared by heating the chloride with silver nitrite for some time on a water-bath, filtering from silver chloride and concentrating the filtrate. It crystallises in colourless glistening leaflets. 

Hadjidemetriou [25] has carried out a comparative study of the determination of nitrates in calciferous soils by the phenoldisulfonic acid and the chromotropic acid spectrophotometric methods. He used 0.02 N cupric sulfate as soil extractant. Silver sulfate was added to remove chlorides. Nitrites, if present, were eliminated by acidifying the extract with N in sulfuric acid. The phenol disulfonic acid method is subject to interference by other ions. Details of the chromotropic acid method are given below. 

The method requires minimal sample pretreatment, allowing for precise measurements of trace levels of selenite in the presence of high background levels of chloride, nitrites and phosphate. Interfering chloride ions were removed by reduction with a silver-saturated cation exchange resin. The detection limit for selenite was 3 xg/l of soil extract and the standard deviation was 6.7% with soil extracts of (0.5 mg/1). Between 0.5 and 99.6 xg/l of selenite were found in soil extracts. 

Silver nitrate solution no precipitate in neutral solution or in the presence of dilute nitric acid. Upon the addition of a little pure (chloride-free) sodium nitrite to the dilute nitric acid solution, a white precipitate of silver chloride is obtained because of the reduction of the chlorate to chloride (see reaction 3 above). 

Upon treatment of the filtrate from 1 with sodium nitrite solution, chlorate and bromate are reduced to the simple halides, the presence of which is revealed by the separation of silver chloride and silver bromide respectively. Chromates (which, of course, yield a coloured solution) are simultaneously reduced to chromium(III) salts. 

While the Thiele process is conducted in alkaline media, Hodgkinson [98] obtained a patent for oxidizing hydrazine with nitrite in neutral solution. The produced azide was precipitated as silver azide and the latter in bulk agitated with common salt to form sodium azide and silver chloride. 

Histidine hydrochloride (2 g.) is suspended in concentrated hydrochloric acid and slowly treated with silver nitrite (3 g.). After removal of excess nitrous acid and silver chloride, the liquid is concentrated to a sirup, which is taken up in alcohol, treated with an excess of alcoholic trimethylamine solution, and kept at 80° for 8 hours. After removal of the alcohol the product is precipitated with phosphotungstic acid. The phosphotungstate is decomposed with barium hydroxide in the usual manner, and the solution of the base thus obtained is strongly concentrated to remove trimethylamine, treated with hydrochloric acid, and the resulting chloride is taken up in alcohol and precipitated with chloroplatinic acid. It is finally converted into the chloroaurate, m.p. 183° with decomposition (14).

Modern potentiometry with variety of classical and membrane sensing electrodes has, so far, rather occasionally been used in ion-chromatography. The first applications of poten-tiometric detection appeared in mid-seventies, when it was utilized for very sensitive detection of halide with silver/silver chloride electrode, and nitrate and nitrite with liquid-state membrane nitrate electrode.In later works number of indicating electrodes used for po-tentiometric detection has significantly increased. A list of reported applications is shown in Table 1.

In a 200 ml. distilling flask place 64 g. (50 ml.) of dry n-butyl bromide and 80 g. of dry silver nitrite (1). Insert a reflux condenser, carrying a cotton wool (or calcium chloride) guard tube, into the mouth of the flask and close the side arm with a small stopper. Allow the mixture to stand for 2 hours heat on a steam bath for 4 hours (some brown fumes are evolved), followed by 8 hours in an oil bath at 110°. Distil the mixture and collect the fraction of b.p. 149-151° as pure 1-nitro-n-butane (18 g.). A further small quantity may be obtained by distilling the fractions of low boihng point from a Widmer flask. 

Atomic hydrogen is a powerful reducing agent, even at room temperature. For example, it reacts with the oxides and chlorides of many metals, including silver, copper, lead, bismuth, and mercury, to produce the free metals. It reduces some salts, such as nitrates, nitrites, and cyanides of sodium and potassium, to the metallic state. It reacts with a number of elements, both metals and nonmetals, to yield hydrides such as NH3, NaH, KH, and PH3. Sulfur forms a number of hydrides the simplest is H2S. Combining with oxygen, atomic... 

Primary alkyl iodides and bromides are excellent substrates for the Victor Meyer reaction, providing a route to both substituted and unsubstituted nitroalkanes (Table i. i).63,65,70,7i formation of the corresponding nitrite ester is a side-reaction and so the nitroalkane is usually isolated by distillation when possible. The reaction of primary alkyl chlorides with silver nitrite is too slow to be synthetically useful. Secondary alkyl halides and substrates with branching on...
