  • Sodium Hydrosulfide - an overview ScienceDirect Topics

    Sodium Hydrosulfide. Sodium hydrosulfide is used more as a common commercial form than sodium sulfide. It is prepared by absorption of hydrogen sulfide in sodium hydroxide. It is shipped as a 45% solution with a specific gravity of 1.303 and a pH of 10.4. The viscosity is 7 centipoise. The solution tends to crystallize below 62°F (17°C).

    OverviewStructure and propertiesPreparationApplications

    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, Na
