Barium yombala hydroxide. Yini esiyaziyo ngaye?

Barium yombala - kuyinto element kwamakhemikhali ishadi lesikhathi ukuthi ihlangana emanzini futhi acid izixazululo. It yakha barium yombala hydroxide kabani Ifomula Ba (OH) 2 (igama wendabuko "barite caustic"). Lena into eziyinkimbinkimbi wezinto ezingaphili. Ngaphandle-ke has ngesimo powder emhlophe, ehlanganisa zinhlayiya okusobala. Le into iyashesha oncibilikayo emanzini - kanye nezinga lokushisa elizosetshenziswa amanzi ephakeme, i-solubility kangcono. "Amanzi Barite" (noma ayegcwele barium yombala hydroxide isixazululo) okukhulunywe amanzi lapho siphela Ba (OH) 2. Barium yombala hydroxide iyaphendula ngokukhululekile carbon dioxide, ngakho-ke ikhambi layo aqueous (noma "amanzi barite") lisetshenziswa ithempulethi yengqikithi njengoba reagent ngoba CO2.

Ngaphezu kwalokho, amanzi barite singasebenza njengesisekelo esiqinile sokufinyelela reagent ukuze sulfate kanye ion carbonate. Nge solubility amanzi ezinhle barium yombala hydroxide kuyinto zingaxazululeki ngokuphelele ukuphuza utshwala ngokweqile. Lesi sici kabanzi emikhakheni eyehlukene yomnotho. Kodwa ngaphambi kokusebenzisa hydroxide, kudingeka ufunde mayelana nendlela ikhiqizwa reagents etholakalayo. Ngakho, hydroxide barium yombala is etholwe Ukuqedwa ngamanzi ashisayo noma ngokubeka amalahle oxide ka barium yombala sulfide e umfudlana esishisa bhé umusi. Lokhu kungafezwa kuphela endaweni yokucwaninga, njengoba ekuphileni kwansuku zonke, le nqubo akuyona kuphela akunakwenzeka, kodwa futhi kuyingozi empilweni yomuntu.

Barium yombala hydroxide isetshenziselwa ukususwa ion sulfate kusukela isilwane futhi zemifino amafutha, izixazululo zezimboni, kanye esetshenziswa ukulungiselela le cesium futhi rubidium hydroxide njengoba isakhi igrisi.

Barium yombala hydroxide anezakhi ezahlukahlukene, kufaka phakathi alikhali. Isetshenziselwa embonini kawoyela ngokwenza uwoyela izithasiselo. Ngaphezu kwalokho, i-hydroxide ezinjalo kubonisa ukuthi kahle ngokwaso njengoba okufakiwe namafutha, ngakho manje-ke kusekelwe esikhiqiza eziningi imikhiqizo efanayo. Non-ayoni yokusansimbi namakhemikhali umkhakha ukusetshenziswa barium yombala hydroxide ezimbonini zabo. Kabanzi njengoba barium yombala oxide hydrate reagent ukuba SO42- futhi CO32-, ngesikhathi yokuhlanza ezilwane kanye zemifino amafutha njengoba igrisi ingxenye, ngenkathi kususwa SO42- kusukela izixazululo ezimbonini.

Ulungiselela Ba usawoti hydroxides, Cs, RB of sulfate zabo noma carbonates akuyona ngaphandle kokusebenzisa reagent ezifana barium yombala hydroxide. Lesi sici futhi isibe eliyisisekelo ekunqumeni ukusetshenziswa ezingase zibe khona ezibangelwa hydroxide embonini. Ngokumangalisayo, barium yombala isetshenziswa ukudala inkanyezi enomsila yokufakelwa: pair of barium yombala, awo adedelwa ebhodini mkhathi, bathambekele kalula ionize yelanga jikisa egqamile plasma efwini.

Ngezinye ngonyaka amahlanu anesithoba kule nkulungwane yeminyaka, lapho iSoviet interplanetary esiteshini okuzenzakalelayo "Luna-1" kwenza indiza yayo, inkanyezi enomsila lokuqala yokufakelwa yadalwa. Physics Melika kanye eJalimane yoma, ukuhlola izinkambu kagesi Zomhlaba, wenza ukukhululwa kwe-barium yombala powder in inani nanhlanu amakhilogremu ngenhla nje Colombia. Lokhu kuholele ekutheni ifu plasma, eyayintula i ijamo side, itholakala eduze kazibuthe amakhulu, okwenza kube lula ukuze ucacise indawo yabo. Iminyaka engamashumi amabili kamuva, izinhlayiya of barium yombala sulfate kanye ne-barium yombala iguqulwe ukuze Jets yasetshenziswa ekuhloleni i-aurora.

Njengoba ubona avela kubo bonke ngenhla, barium yombala hydroxide kuyinto ngempela ebalulekile e umkhakha yesimanje. Ngaphandle izakhiwo zayo eziyingqayizivele kuyoba nzima ngempela ukuze akwazi ukufeza umsebenzi othile. Siphinde alikwazi ukuthi wadala uma usebenzisa hydroxide reagents kabanzi cishe yonke imikhakha yezomnotho!
