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 ...
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 ...
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.
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.
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 ...
As it is derived from a common transition metal, rather than a group 10 metal, MoS 2 is chosen when price or resistance to sulfur poisoning are of primary concern. MoS 2 is effective for the hydrogenation of nitro compounds to amines and can be used to produce secondary amines via reductive amination . [ 42 ]
The described chemistry is also the basis of the doctor test for the sweetness or sourness of gasoline (i.e., the extent of sulfur contamination). A gasoline is described as doctor sweet if, after shaking with sodium plumbite solutions, the addition of powdered sulfur fails to produce a dark precipitate of lead sulfide.
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.
