  2. Ammonium thiosulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_thiosulfate

    Ammonium thiosulfate (ammonium thiosulphate in British English) is an inorganic compound with the formula [NH 4] 2 S 2 O 3. It is white crystalline solid with ammonia odor, readily soluble in water , slightly soluble in acetone and insoluble in ethanol and diethyl ether .

  3. Labeling of fertilizer - Wikipedia

    en.wikipedia.org/wiki/Labeling_of_fertilizer

    In Australia, macronutrient fertilizers are labeled with an "N-P-K-S" system, which uses elemental mass fractions rather than the standard N-P-K values and includes the amount of sulfur (S) contained in the fertilizer. [5] Fertilizers with additional macronutrients (S, Ca, Mg) may add more numbers to the N-P-K ratio to indicate the amount. The ...

  4. UAN - Wikipedia

    en.wikipedia.org/wiki/UAN

    The combination of urea and ammonium nitrate has an extremely low critical relative humidity (18% at 30 °C) and can therefore only be used in liquid fertilizers. The most commonly used grade of these fertilizer solutions is UAN 32.0.0 (32%N) known as UN32 or UN-32, which consists of 45% ammonium nitrate , 35% urea and only 20% water.

  5. Potassium thiosulfate - Wikipedia

    en.wikipedia.org/wiki/Potassium_thiosulfate

    Potassium thiosulfate is commonly used as a fertilizer alone or with urea and/or urea ammonium nitrate [4] due to its ability to delay nitrification. [2] It thus has the ability to reduce the emission of nitrous oxide. [5] It can also reduce the amount of fumigants being released from the soil. [6]

  6. Ammonium sulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_sulfate

    Ammonium sulfate (American English and international scientific usage; ammonium sulphate in British English); (NH 4) 2 SO 4, is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur.

  7. Thiosulfate - Wikipedia

    en.wikipedia.org/wiki/Thiosulfate

    Thiosulfate (IUPAC-recommended spelling; sometimes thiosulphate in British English) is an oxyanion of sulfur with the chemical formula S 2 O 2− 3.Thiosulfate also refers to the compounds containing this anion, which are the salts of thiosulfuric acid, such as sodium thiosulfate Na 2 S 2 O 3 and ammonium thiosulfate (NH 4) 2 S 2 O 3.

  8. Transition metal thiosulfate complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal...

    Sodium thiosulfate and ammonium thiosulfate have been proposed as alternative lixiviants to cyanide for extraction of gold from ores [8] and printed circuit boards. [9] The complex [Au(S 2 O 3) 2] 3-is assumed to be the principal product in such extractions. Presently cyanide salts are used on a large scale for that purpose with obvious risks. [8]

  9. Ammonium sulfite - Wikipedia

    en.wikipedia.org/wiki/Ammonium_sulfite

    Ammonium sulfite is used as a preservative for fixers in photography. When film photographs are being developed ammonium sulfite can be one of the reducing agents used to preserve the hypo (sodium thiosulfate or ammonium thiosulfate). [7] Ammonium sulfite can also be used in the making of bricks. The bricks made using ammonium sulfite are ...
