Product Description

Basic Information Product Name: Sodium Hydrosulfide Other Names: Sodium sulfohydrate; sodium hydrosulphide; Sodium Hydrogen Sulphide; Sodium Hydrogen Sulfide; Sodium Sulfhydrate; sodium bisulfide Molecular Formula: NaHS UN No.: 2949 HS No.: 2830109000 CAS No.: 16721-80-5 EINECS No.: 240-778-0 Hazard Class: 8 Purity: 70% Appearance: Yellow Flakes Grade Standard: Industrial Grade
Physical and Chemical Properties
Sodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the half-neutralization of hydrogen sulfide (H2S) with sodium hydroxide. NaHS is a useful reagent for the synthesis of organic and inorganic sulfur compounds, sometimes as a solid reagent, more often as an aqueous solution. Solid NaHS is colorless, and typically smells like H2S owing to hydrolysis by atmospheric moisture. In contrast with sodium sulfide (Na2S), which is insoluble in organic solvents, NaHS, being a 1:1 electrolyte, is more soluble. Alternatively, in place of NaHS, H2S can be treated with an organic amine to generate an ammonium salt. Solutions of HS− are sensitive to oxygen, converting mainly to polysulfides, indicated by the appearance of yellow.
