Nitrate, potassium silver

Potassium dichromate/nitrate/persulphate Silver nitrate... 

After the addition of silver nitrate, potassium nitrate is added as coagulant, the suspension is boiled for about 3 minutes, cooled and then titrated immediately. Desorption of silver ions occurs and, on cooling, re-adsorption is largely prevented by the presence of potassium nitrate.

Write the net ionic equation for (a) the reaction of copper solid with silver nitrate to form copper(II) nitrate and silver solid, and (b) the reaction of copper solid with potassium nitrate that would form copper(II) nitrate and potassium solid. 

Red phosphorus, sulfur but with carbon, the observed ignition has been attributed to presence of impurities mercury iodide, potassium iodide, silver nitrate, potassium carbonate.

Yellow phosphorus ignites in molten ammonium nitrate, and mixtures of phosphorus with ammonium nitrate, mercuiy(I) nitrate or silver nitrate explode on impact. Red phosphorus is oxidised vigorously when heated with potassium nitrate [1]. During development of new refining agents for aluminium manufacture, a mixture containing red phosphorus (16%) and sodium nitrate (35%) was being pressed into 400 g tablets. When the die pressure was increased to 70 bar, a violent explosion occurred [2],...

After 2xh hours the gas flow is terminated and the power supply is disconnected. The layer of brown oil formed in the bottom of the vessel contains no indium and can be rejected. The supernatant is carefully removed to a 100-mL round-bottomed flask, and the solvent is removed by pumping in vacuo at room temperature until the volume is reduced to about 15 mL. The resultant white solid is collected and washed quickly with several small volumes of diethyl ether although indium(III) chloride is soluble in diethyl ether, the rate of dissolution is fairly slow, and the losses in this washing are tolerable. The collection and washing operations are carried out under dry nitrogen. Yield 0.23 g (26%, based on indium consumed). Anal. Calcd. for InCU In, 51.9 Cl 48.1. Found In (atomic absorption), 51.9 Cl (silver nitrate-potassium thiocyanate titration) 48.8. 

Finally, it being established that (he solution contains mercury, the identification of it, as the bichloride, may be easily effected by solutions of nitrate of silver, caustic ammonia, iodide of potassium, and protocbloride of tin. 

It is important to observe in this process that the mcasuro in which the developer is mixed Bhould be chemically clean it ought, therefore, to be cleansed with cyanide of potassium, and well washed after every picture. In the ordinary wet process it is not absolutely necessary to take this precaution, although it is well to do so. The nitrate of silver added to the developer should be fresh solution, and not taken from the nitrate-bath. 

To Excite the Plate.—Place it on a dipper, and immerse it quickly and without hesitation in a vertical bath of acetonllrata of silver, made thus —Distilled water one ounce, nitrate of silver fifty grains, glacial acetic acid one drachm. Leave It in the bath for a couplo of minutes, then wash it well in clean watar, and lastly in distilled watar, and set it up to dry. When dry put it away in the platebox until ready for use in the camera. It may be preserved in a sensitive state for several days. Some persons add a few drops of a solution of iodide of potassium to a new nitrate-bath, and filter it on the following day, in order to saturate it with iodide of silver. When this is done a new bath is not so liable t attack the iodide of silver in the film. 

The solution called double iodide is made by dissolv. lug twenty grains of nitrate qf silver in one ounce of distilled water, and adding crystals of iodide of potassium, a few at a time, until the yellow turbidity at first produced io the solution is quite cleared up. The quantity required is nearly half an ounce. The menstruum should be filtered before use.. 

Printing "by Development.—Hollingwohth b thin paper is to be preferred to any other. Immerse it in a solution containing Bix grains of Balt and one part of iodide of potassium to the ounce of rain water. When dry, brush oyer, it, precisely as in the ammonio-nitrate process, the following solution of nitrate of silver —... 

Sulphates and Chlorides. — Boil 0.5 gm. of potassium permanganate with a mixture of 2 cc. of 95 per cent alcohol and 25 cc. of water, and filter. The filtrate should be colorless, and, after adding to it 2 cc. of nitric acid, barium nitrate, and silver nitrate solutions, it should not develop more than a slight opalescence. 

All the reagents listed can be used to cleave trimethylsilyl groups from acetylenes fluoride, potassium carbonate under basic conditions in methanol, or silver nitrate/potassium cyanide.9 With the third method advantage can be taken of the fact that the later transition metals (e.g., copper or silvei) complex readily with acety-lides. Workup with concentrated potassium cyanide solution causes compound 32 to be cleaved tu alkyne 33. In this way silylated a -kynes can be deprotected in the presence of 0-silyl groups.
