It contributes no color to bisulfide salts, and its salts may have a distinctive putrid smell. It is a strong base. Bisulfide solutions are corrosive and attack the skin.It is an important chemical reagent and an industrial chemical, mainly used in paper pulp industry (Kraft process), textiles, synthetic flavors, coloring brasses, and iron control.Table of Contents       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Properties[edit]Basicity[edit]Chemical reactions[edit]Biochemistry[edit]Other derivatives[edit]See also[edit]References[edit]Properties[edit]A variety of salts are known, including sodium hydrosulfide and potassium hydrosulfide. Ammonium hydrosulfide, a component of “stink bombs” has not been isolated as a pure solid. Some compounds described as salts of the sulfide dianion contain primarily hydrosulfide. For example, the hydrated form of sodium sulfide, nominally with the formula Na2S \u00b7 9 H2O, is better described as NaSH \u00b7 NaOH \u00b7 8 H2O.  The UV\u2013visible spectrum of septic sewage from three different sites. The absorption of bisulfide is observed around 230\u00a0nm in each case.Aqueous bisulfide absorbs light at around 230\u00a0nm in the UV\u2013visible spectrum.[1] Using this approach, bisulfide has been detected in the ocean[2][3] and in sewage.[4]Bisulfide should not be confused with the disulfide dianion, S2\u22122, or \u2212S\u2013S\u2212.Basicity[edit]The bisulfide anion can accept a proton:(1)Because of its affinity to accept a proton (H+), bisulfide has a basic character. In aqueous solution, it has a corresponding pKa value of 6.9. Its conjugate acid is hydrogen sulfide (H2S). However, bisulfide’s basicity stems from its behavior as an Arrhenius base. A solution containing spectator-only counter ions, has a basic pH according to the following acid-base reaction:HS\u2212 + H2O "},{"@context":"http:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki24\/#breadcrumbitem","name":"Enzyklop\u00e4die"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki24\/bisulfide-wikipedia\/#breadcrumbitem","name":"Bisulfide – Wikipedia"}}]}]
