Yini i-sodium ne-hydrogen sulfate?

Sodium sulfate - kuyinto usawoti acid sodium kanye sulfuric acid. Ezikhonjiswe NaHSO4 izimangalo izidakamizwa. Sodium sulfate kuyinto crystal esobala abangenalo iphunga othize. Ungqimba izinyo lomhlathi we ketshezi ilingana 120,06 amagremu imvukuzane ngalinye, futhi kwabantu - 2,472 igremu ngayinye isentimitha cubic. Lincibilike ezingeni lokushisa +186 ° C. Lapho amalahle ketshezi kungabonakala nasemkhakheni inguqulelo ezimbili polymorphic - ezingeni lokushisa +140 ° C +170 ° C.

Sodium sulfate kungenziwa wasithukuthelela alikhali, labona zasabela kanjani sulfate. Ngakho, ngo-ukusabela ngayo sodium hydroxide kwakhiwa sodium sulfate namanzi. Uma Ukushisa eqinile ukwaziswa okufanayo (kufika ku +250 ° C noma ngaphezulu) ke ihlukaniselwe sodium pyrosulfate namanzi.

Nokho, Ngokuvamile, sulfate sodium akasabeli nezinye izinto, sintering kwenzeka ezingeni lokushisa mkhulu kunezinhliziyo +450 ° C, okwazi ukusabela nge usawoti oxides.

SIZUZISA yalolu ketshezi mkhulu isisetshenziswa yokusansimbi nonferrous (njengoba ecucuza), futhi uba reagent kule nguqulo oxides sulfate. Kuyinto denaturing eqinile. Ingabe kabanzi ekuphekeni (ngokomthetho njengenkolo ukudla okufakiwe E514).

Nokho, naphezu ukubaluleka kwayo ekuphileni kwebantfu, i-sodium ne-hydrogen sulfate futhi ungaba yingozi: ngokuba alikhali eqinile, ayinto kuyinto onakalisayo kakhulu, nabo isikhumba angashiya ukusha, owabangela umonakalo eside futhi iso. Ingozi embi kunazo zonke is ukuwela pheshana emathunjini. Libuye izidakamizwa eziyingozi kakhulu futhi ephefumula ka evala.

Ngenxa umthelela ongemuhle sodium bisulfate emzimbeni womuntu kuyinto into kuphawulwa uphawu leentjhabatjhaba "Danger" kuyinto orange square, dissected ezimbili idayagonali imivimbo abamnyama. A uphawu lokuthi uthi ngezingozi lomcebo hhayi kuphela abantu kodwa futhi imvelo, kanye yemingcele eyayibekelwe ukukhiqizwa yayo.

Ukuze sodium hydrogensulfate kudingekile ukwenza ukusabela phakathi kanzulu sulfuric acid kanye sodium hydroxide, kanye sulfuric acid kufanele kube ngokweqile. Ngenxa yalokho, lesi simo ukhiqiza sodium bisulfate namanzi.

Nokho, ngaphambi kokuba athathe ekwamukeleni le nto ukuze athole ngokwakhe sodium. Ukulungiselela sodium akuyona kakhulu nzima inqubo, futhi ezinye izindlela zingenzeka ngisho ekhaya.

Eyodwa yezindlela bokuqala zisabela kanjani sodium ukuthola yokutakula sodium carbonate (Na2CO3) e ilahle lokushisa eliphezulu (azungeze +1000 ° C). yi Yasungulelwa ukuthola sodium okumsulwa nokuhlukaniswa kwemihlambi-carbon monoxide. Ukuqhuba basabela kakhulu isikhathi, kodwa ngenxa ukukhululwa kwe-carbon monoxide, kwaba yingozi kakhulu.

Ngakho-ke liye yasungulwa enye indlela sokulungiselela - electrolysis ka oncibilikisiwe sodium chloride. Buhle le ndlela kuyinto ukuphepha hhayi kuphela yayo ehlobene, kodwa futhi ezincane kuno lokushisa ukunciphisa izidakamizwa Ukushisa: +600 ° C esikhundleni +1000 ° C. Okungukuthi, le ndlela ingasetshenziswa ekhaya - uma Yebo, kukhona kungenzeka Ukushisa sodium chloride (usawoti ezivamile) kuya wathi lokushisa.

Ngesisekelo sodium - element amakhemikhali-asebenzayo we ishadi lesikhathi - ukulungele congeners sodium hydrogensulfate futhi kubaluleke kunazo zonke esintwini. Le into - sodium hydrosulfide, usawoti acid kanye sodium-hydrogen sulfide. Limelela zinhlayiya ezimhlophe, okhonjiswe ifomula NaHS. It is etholwe odlulayo hydrogen sulphide ngokusebenzisa isixazululo sodium sulfide ne-hydrogen sulfide by edabula isixazululo sodium hydroxide.

Sodium hydrosulfide ihlangana alkalis futhi acid, ayefaka kalula umoya-mpilo. Ngu ukuncibilika iba abamnyama. It is kabanzi: ingxenye indlela ayisebenzisayo ukususa izingqimba isikhumba esilengayo, kwasakazwa izindwangu, wasebenzisa njengoba impahla eluhlaza ukwenziwa udayi eziningi butifos.
