Mene ne sodium hydrogen sulfate?

Sodium sulfate - ne da acid gishiri na sodium da kuma sulfuric acid. Denoted NaHSO4 da abu siffantawa. Sodium sulfate ne m crystal da ciwon babu takamaiman wari. A matauni taro na abu ne daidai 120,06 grams da mole, da yawa - 2,472 gram da cubic santimita. Yana narke a zazzabi na +186 ° C. Bayan dumama abu za a iya lura biyu polymorphic mika mulki - at zazzabi na +140 ° C da +170 ° C.

Sodium sulfate za a iya mayar da martani tare da Alkali, wucewa a dauki ga sulfate. Saboda haka, ta maida martani da shi tare da sodium hydroxide kafa sodium sulfate da kuma ruwa. Idan wani karfi da dumama da wannan abu (har zuwa +250 ° C ko fiye) shi ne raba cikin sodium pyrosulfate da ruwa.

Yadda aka saba, da sodium sulfate ba amsa tare da wasu abubuwa, duk da haka, sintering auku a wani zazzabi ya fi +450 ° C, shi ne iya maida martani tare da salts da oxides.

The m darajar wannan abu ne mai girma: shi ne a yi amfani da nonferrous metallurgy (as juyi), shi ma abubuwa a matsayin reagent a cikin translation oxides sulfates. Yana da wani karfi denaturing. An yadu a yi amfani da dafa abinci (hukumance rajista a matsayin abinci ƙari E514).

Duk da haka, duk da muhimmancinsa a rayuwar mutum, sodium hydrogen sulfate kuma iya zama haɗari: zama mai karfi da Alkali, abu ne sosai lalatattu, a lamba tare da fata iya barin mai tsanani konewa, haddasa babba lalacewar da ido. A mafi girma da hadari ne fadowa cikin gastrointestinal fili. Shi ne kuma musamman cutarwa abu da kuma inhalation na vapors.

Saboda da mummunan tasiri na sodium bisulfate a jikin mutum shi ne a abu alama ta kasa da kasa alama ce ta "Hadari" shi ne wani square orange, dissected biyu diagonal baki ratsi. A alamar cewa ya ce game da illar da abu ba kawai ga mutane amma kuma ga yanayi, kazalika da hani sanya a kan ta samar.

Domin sodium hydrogensulfate zama dole yin dauki tsakanin mayar da hankali sulfuric acid da sodium hydroxide, da sulfuric acid da ya kamata a wuce haddi. A sakamakon haka, wannan dauki samar sodium bisulfate da ruwa.

Duk da haka, kafin ka yi a kan samu wannan abu don samun kansa sodium. Shiri na sodium ba ma wuya hanya, da kuma wasu daga cikin hanyoyin su ne yiwu ma a cikin gida.

Daya daga cikin farko hanyoyi ne da dauki na sodium samu dawo da na sodium carbonate (Na2CO3) a wata high zazzabi kwal (a kusa da +1000 ° C). Its sakamakon da aka samu ga m sodium da kuma warewa daga carbon monoxide. Gudanar da dauki ba ma lokaci cinyewa, amma saboda da saki na carbon monoxide, ya zama mai hadarin gaske.

Saboda haka an yi ƙirƙira wani Hanyar shiri - electrolysis na zubi sodium chloride. A amfani da wannan hanya shi ne ba kawai ta zumunta da aminci, amma kuma karami fiye da a rage abu dumama zazzabi: +600 ° C maimakon +1000 ° C. Wannan shi ne, wannan hanya za a iya amfani da a gida - idan, ba shakka, akwai yiwuwar dumama sodium chloride (na kowa gishiri) zuwa ce zazzabi.

A kan tushen da sodium - na chemically-aiki kashi na lokaci-lokaci tebur - shirye congeners sodium hydrogensulfate kuma babu kasa muhimmanci ga bil'adama. Wannan abu - sodium hydrosulfide, acid gishiri da kuma sodium hydrogen sulfide. Yana wakiltar fari lu'ulu'u, denoted da dabara NaHS. An samu ta hanyar wucewa hydrogen sulphide ta hanyar wani bayani da sodium sulfide da hydrogen sulfide ta wucewa ta hanyar sodium hydroxide bayani.

Sodium hydrosulfide reacts tare da alkalis da kuma acid, sauƙi oxidized ta oxygen. By narkewa zama baki. An yadu amfani: wani ɓangare na nufin amfani da su cire wuce haddi fata yadudduka, rarraba a Textiles, amfani da albarkatun kasa domin samar da yawa dyes butifos.
