H2s chemical name

Hydrogen sulfide is best defined as a colorless, flammable gas that contains a smell closely resembling that of rotten eggs. A relatively small chemical, with a molecular weight of 34.1, hydrogen sulfide is commonly found in the environment, both naturally and from human activities. In its gaseous state, it makes sense that hydrogen sulfide likes to hang around other gasses or mingle in gaseous conditions. This applies to nature, where hydrogen sulfide is commonly found in places such as volcanic gas, petroleum gas (unrefined), and hot springs (Diagram 1). And yes, I know you were thinking, 'What about human flatulence (i.e. gas)?' Glad you asked, because hydrogen sulfide is produced as a by-product from bacteria in our intestines. Of course the only way for our bodies to release hydrogen sulfide, is through. . . well, I'm quite sure you can predict what that bodily outlet might be. Diagram 1: Where Hydrogen Sulfide Is Released into the Environment Using the periodic table, we can see that the hydrogen atom falls into the Group 1 category, meaning it only has one valence electron. But wait! We cannot stop right there, as there are two hydrogen's present in the compound hydrogen sulfide. When you multiply by two, it not only makes the total number of valence electrons for hydrogen equal to two, but also keeps hydrogen's outer shell both stable and happy. Hydrogen sulfide is a colorless, flammable, gas that is associated with a rotten egg foul odor. It is found in nature and...

Both are actually correct. For consistency, IUPAC has defined the "parent molecule" as "sulfane" with acceptable "official" names of both "hydrogen sulfide" and "dihydrogen sulfide" (actually preferred, both are "Compositional names" per IUPAC). 17 . #H_2S# dihydrogen(sulfide) Note the difference from compositional names such as ‘hydrogen peroxide’ for #H_2O_2# and ‘hydrogen sulfide’ for #H_2S# (Chapter IR-5) in which (in English) there is a space between the electropositive and electronegative component(s) of the name. Compositional names of the above type, containing the word ‘hydrogen’, were classified as ‘hydrogen nomenclature’ in the discussion of oxoacids in Section I-9.5 of Ref. 2, and such names were extensively exemplified. However, in order to avoid ambiguity, their general use is not encouraged here. Consider, for example, that the compositional names ‘hydrogen sulfide’ and ‘hydrogen sulfide( #2^-#)’ can both be interpreted as #H_2S# as well as #HS^-# . The situation with #H_2S# is completely analogous to that with #Na_2S# which may be named sodium sulfide, disodium sulfide, sodium sulfide(2 ) and disodium sulfide(2 ), except that misinterpretation of the first and third names as denoting NaS is improbable. In Ref. 2, the names ‘hydrogensulfide(1 )’ and ‘monohydrogensulfide’ for #HS^-# were proposed to avoid ambiguity. (However, in some languages there is no space in compositional names so that very delicate distinctions are required anyway.) From: NOMENCLATURE ...

Chemical compound Sodium hydrosulfide is the H 2S) with H 2S owing to hydrolysis by atmospheric moisture. In contrast with Na 2S), which is insoluble in organic solvents, NaSH, being a 1:1 electrolyte, is more soluble. Structure and properties [ ] Crystalline NaHS undergoes two HS − behaves as a spherical anion owing to its rapid rotation, leading to equal occupancy of eight equivalent positions. Below 360K, a HS − sweeps out a discoidal shape. Below 114K, the structure becomes NaSH has a relatively low melting point of 350 °C. In addition to the aforementioned anhydrous forms, it can be obtained as two different hydrates, NaSH·2H 2O and NaSH·3H 2O. These three species are all colorless and behave similarly, but not identically. It can be used to precipitate other metal hydrosulfides, by treatment of aqueous solutions of their salts with sodium hydrosulfide. It is analogous to sodium hydroxide, and is a strong base. Preparation [ ] One laboratory synthesis entails treatment of NaOCH 2CH 3 + H 2S → NaSH + CH 3CH 2OH An alternative method involves reaction of sodium with hydrogen sulfide. Applications [ ] Thousands of tons of NaSH are produced annually. Its main uses are in cloth and paper manufacture as a makeup chemical for References [ ] • Haarmann, F.; Jacobs, H.; Roessler, E.; Senker, J. (2002).
