Carbon disulfide (also spelled as carbon disulphide) is an inorganic compound with the chemical formula CS 2 and structure S=C=S. It is also considered as the anhydride of thiocarbonic acid . [ 8 ] It is a colorless, flammable, neurotoxic liquid that is used as a building block in organic synthesis.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure.
Sodium diethyldithiocarbamate typically crystallizes from water as the trihydrate NaS 2 CN(C 2 H 5) 2. 3H 2 O. The anhydrous salt and the trihydrate are often used interchangeably. [1] Sodium diethyldithiocarbamate is obtained by treating carbon disulfide with diethylamine in the presence of sodium hydroxide: CS 2 + HN(C 2 H 5) 2 + NaOH → NaS ...
Many secondary amines react with carbon disulfide and sodium hydroxide to form dithiocarbamate salts: [2] R 2 NH + CS 2 + NaOH → R 2 NCS − 2 Na + + H 2 O. Ammonia reacts with CS 2 similarly: 2 NH 3 + CS 2 → H 2 NCS 2 − NH 4 + Dithiocarbamate salts are pale colored solids that are soluble in water and polar organic solvents.

Triple superphosphate (TSP) typically consists of 44–48% of P 2 O 5 and no gypsum. A mixture of single superphosphate and triple superphosphate is called double superphosphate. More than 90% of a typical superphosphate fertilizer is water-soluble. The main potassium-based straight fertilizer is muriate of potash (MOP, 95–99% KCl). It is ...
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
Phosphorus pentasulfide is the inorganic compound with the formula P 2 S 5 or P 4 S 10 . This yellow solid is the one of two phosphorus sulfides of commercial value. Samples often appear greenish-gray due to impurities. It is soluble in carbon disulfide but reacts with many other solvents such as alcohols, DMSO, and DMF. [3]
