  2. Hydrogen sulfide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_sulfide

    Molar mass: 34.08 g·mol −1 Appearance Colorless gas Odor: Foul, pungent, like that of rotten eggs ... Hydrogen sulfide is a chemical compound with the formula H 2 S.

  3. Sulfide - Wikipedia

    en.wikipedia.org/wiki/Sulfide

    The sulfide ion does not exist in aqueous alkaline solutions of Na 2 S. [3] [4] Instead sulfide converts to hydrosulfide: S 2− + H 2 O → SH − + OH −. Upon treatment with an acid, sulfide salts convert to hydrogen sulfide: S 2− + H + → SH − SH − + H + → H 2 S. Oxidation of sulfide is a complicated process.

  4. Bisulfide - Wikipedia

    en.wikipedia.org/wiki/Bisulfide

    Molar mass: 33.07 g·mol −1 Conjugate acid: Hydrogen sulfide: ... When strongly heated, bisulfide salts decompose to produce sulfide salts and hydrogen sulfide.

  5. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.

  6. Sodium hydrosulfide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydrosulfide

    Molar mass: 56.063 g/mol Appearance off-white solid, deliquescent: ... This compound is the product of the half-neutralization of hydrogen sulfide (H 2 S) ...

  7. Iron(II) sulfide - Wikipedia

    en.wikipedia.org/wiki/Iron(II)_sulfide

    Molar mass: 87.910 g/mol Appearance Grey, sometimes in lumps or powder ... Some of the hydrogen sulfide will react with metal ions in the water or solid to produce ...

  8. Ammonium hydrosulfide - Wikipedia

    en.wikipedia.org/wiki/Ammonium_hydrosulfide

    The mixture easily converts to ammonia and hydrogen sulfide gases. This conversion illustrates the ease of the following equilibrium: [NH 4]SH ⇌ NH 3 + H 2 S. Ammonia and hydrogen sulfide each have a powerful and unpleasant smell. Solid ammonium hydrosulfide can be produced by reacting an equimolar mixture of ammonia and hydrogen sulfide ...

  9. Potassium hydrosulfide - Wikipedia
