Highly toxic and a dangerous fire risk in contact with organic materials, It has been used for the nitration of aromatic organic compds and in the prepn of MF... 

The film formed during the blank test was left on the glassy carbon surface. Upon addition of further mercury nitrate, 20-50 til of a 5 g/1 solution were... 

Elemental composition Li 16.37%, Cl 83.63%. The aqueous solution of the salt may be analyzed for lithium metal by AA or ICP (See Lithium) and for chloride by titration against a standard solution of silver nitrate or mercury nitrate, or by ion chromatography. 

Mercury chloride is obtained as a white precipitate by adding a cold acidic solution of sodium chloride or other soluble chloride to a solution of mercurous salt, such as mercury nitrate ... 

However, on strong heating, mercury nitrate decomposes to mercury metal Hg(N03)2 Hg + 2NO2 + O2... 

According to Wieland, reactions between mercury nitrate, nitric acid and alcohol leading to the formation of mercury fulminate proceed as follows ... 

Fig. 38. General view of plant for manufacturing mercury fulminate in Atlas Powder Company, according to Davis [62]. On the left, conical flasks with mercury nitrate in nitric acid. On the right, reaction flasks.

Mercury nitrate, corrosive sublimate, white arsenic, and lead acetate are occasionally used as reagents, and soap is described as an indication of hard waters, as when added to them a decomposition takes place, the acid unites with alkali, and the oil is disengaged such waters as these are generally called hard waters, and are unfit for washing cloaths, as also for boiling pulse and the harder kinds of flesh. 18 The list of qualitative reagents for the many constituents of natural waters comprises the principal reagents in use at present. 

A 0.26-g sample of mercury was produced from a mercury nitrate aqueous solution when a current of 210 mA was applied for 1200 s. What is the oxidation number of the mercury in the mercury nitrate ... 

Kunckel s meaning in the last sentence is evidently that mercury nitrate reacts with alcohol on warming, and that silver nitrate does not react with alcohol under the same conditions. 

The nitroisonitrosoacetic acid loses carbon dioxide to form formonitrolic acid which (6) decomposes further into nitrous acid and fulminic acid, and (7) the fulminic acid reacts with the mercury nitrate to form the sparingly soluble mercury fulminate which precipitates. 

When solid mercury carbonate, Hg2C03, is added to nitric acid, HN03, a reaction occurs to give mercury ) nitrate, Hg(N03)2, water, and two gases A and B ...

Ammonia is evolved (odour turns red litmus paper blue turns mercury nitrate paper black). 

Test for ammonium ions Boil a little (c. 0 1 g) of the substance with sodium hydroxide solution. The evolution of ammonia, detected by its odour and its action upon red litmus paper and upon filter paper soaked in mercury nitrate solution, indicates the presence of an ammonium salt. 

Nitrate in the presence ofbromide and iodide Treat 10-15 mg of the substance with 1 ml sodium hydroxide solution and 10-15 mg of Devarda s alloy (or of aluminium as powder or as thin foil), place in the hot water rack, and test for ammonia with red litmus paper or mercury nitrate paper (Fig. II.30a). 

Mercury chloride (calomel) suspension. To 5 ml of 0 05m mercury nitrate add 1 ml of 2m hydrochloric acid. Wash the precipitate 5 times with 10 ml water by decantation. Suspend the precipitate finally with 5 ml water. 

Mercury nitrate (0 05m). Dissolve 28 1 g mercury nitrate dihydrate, Hg2(N03)2.2H20, in a cold mixture of 500 ml water and 10 ml concentrated nitric acid. Dilute with water to 1 litre. Add 1 drop of pure mercury metal to prevent oxidation. 

Mercury ) nitrate (0 05m). Dissolve 17.1 g mercury ) nitrate monohydrate, Hg(N03)2.H20, in water and dilute the solution to 1 litre. 

Summary MZ is easily prepared by mixing solutions of sodium azide and mercury-II-nitrate. The precipitated product is then carefully filtered-off, washed, and dried in a dissector. The dried product may contain some mercury nitrate, and/or mercury-II-oxide. 

Summary HGNTA is similar to CNTA in nature, and can be made by converting CNTA to the sodium salt, which is much more soluble in water. This sodium salt gives way to the insoluble mercury salt when treated with mercury nitrate in the presence of nitric acid. The precipitated mercury salt is then collected by filtration, washed, and dried.
