  2. Toxicology of red imported fire ant venom - Wikipedia

    en.wikipedia.org/wiki/Toxicology_of_red_imported...

    The recommended maintenance dose is between 0.5 mL of a 1:100 w/v 1:10 w/v WBE. [66] For fire ant venom immunotherapy, the most common maintenance dose is 0.5 mL of a 1:200 (wt/vol) dilution. [67] During the build-up phase, it is recommended that dosing is given weekly or biweekly, although some scientists suggest that rush protocols can be ...

  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. 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 ...

  5. 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.

  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. 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.

  9. Methylsulfonylmethane - Wikipedia

    en.wikipedia.org/wiki/Methylsulfonylmethane

    The claims for the need for sulfur supplementation originate with Robert Herschler, a biochemist who filed a patent for using MSM as a dietary supplement in 1982. [ 25 ] Moreover, in cases involving topical therapeutics, the role of MSM as an active agent, per se, versus its having a role in promoting skin permeation (in manner, akin to its ...
