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.
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.
Molar mass: 33.07 g·mol −1 Conjugate acid: Hydrogen sulfide: ... When strongly heated, bisulfide salts decompose to produce sulfide salts and hydrogen sulfide.
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.
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) ...
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 ...
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 ...
Molar mass: 72.171 g/mol Appearance white solid Density: ... It is the product of the half-neutralization of hydrogen sulfide with potassium hydroxide.
