Formula : NAHS
Sodium hydrosulfide is the chemical compound with the formula NaSH. Other names include sodium bisulfide, sodium sulfhydrate, sodium hydrogen sulfide and Nash. This species is the product of the half -neutralization of hydrogen sulfide with a sodium-derived base. NaSH is a useful reagent for the synthesis of organic and inorganic sulfur compounds. It is a colorless solid that typically smells like H2S due to hydrolysis by atmospheric moisture. In contrast with Na2S, which is insoluble in organic solvents, NaSH, being a 1:1 electrolyte, is more soluble. Alternatively, in place of NaSH, H2S can be treated with an organic amine to generate an ammonium salt. Solutions of SH- are sensitive to oxygen, converting mainly to polysulfides, indicated by the appearance of yellow.
