  2. Lime sulfur - Wikipedia

    en.wikipedia.org/wiki/Lime_sulfur

    Lime sulfur reacts with strong acids (including stomach acid) to produce highly toxic hydrogen sulfide (rotten egg gas) and indeed usually has a distinct "rotten egg" odor to it. Lime sulfur is not flammable but can release highly irritating sulfur dioxide gas when in a fire. Safety goggles and impervious gloves must be worn while handling lime ...

  3. Hydrogen sulfide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_sulfide

    It is slightly soluble in water and acts as a weak acid (pK a = 6.9 in 0.01–0.1 mol/litre solutions at 18 °C), giving the hydrosulfide ion HS −. Hydrogen sulfide and its solutions are colorless. When exposed to air, it slowly oxidizes to form elemental sulfur, which is not soluble in water. The sulfide anion S 2− is not formed in aqueous ...

  4. Sulfide - Wikipedia

    en.wikipedia.org/wiki/Sulfide

    Sulfide (also sulphide in British English) [2] is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.

  5. Catalyst poisoning - Wikipedia

    en.wikipedia.org/wiki/Catalyst_poisoning

    Poisoning often involves compounds that chemically bond to a catalyst's active sites. Poisoning decreases the number of active sites, and the average distance that a reactant molecule must diffuse through the pore structure before undergoing reaction increases as a result. [4] As a result, poisoned sites can no longer alter the rate of reaction ...

  6. Phosphorus sulfides - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_sulfides

    Phosphorus sulfides comprise a family of inorganic compounds containing only phosphorus and sulfur.These compounds have the formula P 4 S n with n ≤ 10. Two are of commercial significance, phosphorus pentasulfide (P 4 S 10), which is made on a kiloton scale for the production of other organosulfur compounds, and phosphorus sesquisulfide (P 4 S 3), used in the production of "strike anywhere ...

  7. Polysulfide - Wikipedia

    en.wikipedia.org/wiki/Polysulfide

    The alkali metal polysulfides arise by treatment of a solution of the sulfide with elemental sulfur, e.g. sodium sulfide to sodium polysulfide: S 2− + n S → S 2− n+1. In some cases, these anions have been obtained as organic salts, which are soluble in organic solvents. [4]

  8. Sodium polysulfide - Wikipedia

    en.wikipedia.org/wiki/Sodium_polysulfide

    Sodium polysulfide can be produced by dissolving sulfur in a solution of sodium sulfide. [4] Alternatively they are produced by the redox reaction of aqueous sodium hydroxide with sulfur at elevated temperatures. [5] Finally they arise by the reduction of elemental sulfur with sodium, a reaction often conducted in anhydrous ammonia.

  9. Sulfur water - Wikipedia

    en.wikipedia.org/wiki/Sulfur_water

    Sulfur water (or sulphur water) is a condition where water is exposed to hydrogen sulfide gas, giving it a distinct "rotten egg" smell. This condition has different purposes in culture varying from health to implications for plumbing.
