Ammonium nitrate 1278 INDEX

Available K measured by ammonium nitrate gave a good indication of plant available K in the soil for organic systems, but not all extractable K is truly available. The K index system can be used as a reasonable guide for organic systems. 

I. 03N.NH2(CH2CH20N02)2 [called di(/3-nitroxy-ethyl)ammonium nitrate in Blatt not found in CA index]... 

Properties Soft, blue-white, malleable metal or grayish-white powder. D 8.642, mp 320.9C, bp 767C,refr index 1.13, Mohs hardness 2.0. Soluble in acids, especially nitric, and in ammonium nitrate solution. Lowers melting point of certain alloys when used in low percentages. Tarnishes in moist air. Corrosion resistance poor in industrial atmo-... 

Given that inorganic filler is a mixture of salts (potassium, magnesium ehlo-rides magnesium sulfates potassium and ammonium nitrates), it was shown (Table 1.2) that exactly nitrogen-containing salts led to a significant increase of the melt flow index in sevilene-based PCMs.

The anhydrous salt yields yellowish-white crystals of density2 7-3 at 15° C. and melting point 3 1042° C. The specific heat is 4 0-0728 and the molar heat 05-4. The index of refraction is 2 2-14. It is insoluble in water, aqueous ammonia and in solutions of ammonium salts,5 and only slightly soluble in aqueous alkali or brine.6 It is decomposed when heated with hydrogen chloride,7 forming lead and arsenic chlorides, and in hot nitric acid it dissolves to form arsenic acid and lead nitrate, the latter being precipitated if the acid is sufficiently concentrated.8... 

Several platinum compounds, including trimethylplatinum derivatives, are explosively unstable. Some compounds of the other platinum group metals are also of limited stability. Individually indexed compounds are Amminedecahydroxydiplatinum, 4588 Amminepentahydroxyplatinum, 4566 Ammonium hexachloroplatinate, 4180 Ammonium tetranitroplatinate(II), 4573 Diacetatoplatinum(II) nitrate, 1507 Diamminedichloroamidotrichloroplatinum(IV), 4173... 

Cleaning of SPR glass slides (optical grade SF2, refractive index 1.65, from UQG Optical Components). Sonicator (e.g., Lucas Dawe sonication bath) and different solutions hydrochloric acid/nitric acid 3 1 v/v (solution A) ammonium cerium nitrate (1M) (solution B) sulfuric acid/hydrogen peroxide 1 1 (Piranha solution) isopropanol. Use caution in handling these solutions harmful and corrosive.

Some aspects of water quality can also be determined by methods involving distillation these include determination of phenol index , nitrate content, and ammonium content.
