Barium hydroxide. Re tseba eng ka eena?

Barium ke lisebelisoa tsa lik'hemik'hale tsa tafoleng ea li-periodic tse sebetsang ka metsi le motsoako oa acid. E bōpa barium hydroxide, e leng mofuta oa Ba (OH) 2 (lebitso la moetlo ke "barite e kotsi"). Ena ke ntho e rarahaneng e sa tloaelehang. Ka ntle ho bonahala eka ke phofo e tšoeu, e nang le likristale tse hlakileng. Ntho ena e qhibiliha haholo metsing - 'me e phahame ka mocheso oa metsi, e ntlafatsa bolutu ba tsona. "Metsi a Baryte" (kapa tharollo e phethehileng ea barium hydroxide) e bua ka metsi ao Ba (OH) 2 a qhibilihang ho 'ona. Barium oxide hydrate e ikemela ka bolokolohi le carbon dioxide, ka hona, tharollo ea eona ea metsi (kapa "metsi a barite") e sebelisetsoa ho hlahloba lik'hemik'hale e le phetoho ea CO2.

Ho phaella moo, metsi a barite a ka sebetsa e le reagent bakeng sa lione tsa sulfate le carbonate. Ka ho itšehla hantle metsing, barium hydroxide ha e kene ka ho feletseng ka joala. Karolo ena e sebelisoa haholo ho makala a sa tšoaneng a moruo oa naha. Empa pele u sebelisa ena hydroxide, u lokela ho fumana hore na e fumanoa joang ho li-reagents tse teng. Kahoo, barium hydroxide e fumanoa ka ho qhibiliha ka metsi a chesang a metsi kapa ka ho futhumatsa sulfide ea barium molaong oa mouoane o matla haholo. Sena se finyelloa feela laboratory, kaha bophelong ba letsatsi le leng le le leng mokhoa ona ha o khonehe feela, empa o kotsi hape bakeng sa bophelo bo botle ba batho.

Barium hydroxide e sebelisoa ha ho tlosoa li-ions tsa sulphate lihlahisoa tsa liphoofolo le limela tsa meroho, lihlahisoa tsa indasteri, hape li sebelisetsoa ho hlahisa rubidium le cesium hydroxides e le lisebelisoa tsa lisebelisoa.

Barium hydroxide e na le mefuta e mengata, ho akarelletsa le alkaline. E sebelisoa indastering ea oli, ho etsa li- additives bakeng sa oli. Ho feta moo, hydroxide ea mofuta ona e iponahatsa e le ho eketsa mafura, kahoo hona joale motheong ona o hlahisa lihlahisoa tse ngata tse tšoanang. Metallurgy eo e seng ea ferra le indasteri ea lik'hemik'hale e sebelisa barium hydroxide liindastering tsa tsona. Ho sebelisoa libaka tse ngata tsa barium oxide hydrate e le reagent ho SO42- le CO32-, ho hloekisoa ha mafura a liphoofolo le oli ea meroho, e le karolo ea motlakase, ha SO42- e tlosoa lits'ebetsong tsa indasteri.

Ho lokisoa ha Ba salts le hydroxide ea Cs, Rb ho tloha ho sulfates kapa carbonates ea bona ha ho sebelisoe reagent e kang barium hydroxide. Tšobotsi ena e boetse e fetohile ea bohlokoa tabeng ea ho sebelisa mokhoa o ka sebelisoang ha hydroxide ena lefapheng. Ho tsotehang hore ebe barium e sebelisetsoa ho etsa litšoantšo tsa maiketsetso: lihlopha tsa barium tse lokollang sefofaneng li na le bokhoni ba hore li fumanehe habonolo ke mahlaseli a letsatsi ebe li fetoha maru a khanyang a pula.

Lilemong tse mashome a mahlano a metso e robong tsa millennium ea ho qetela, ha lipolanete tsa Soviet lipakeng tsa Luna-1 tsa Soviet li ile tsa e-ba teng, ho ile ha bōptjoa motsoako oa pele oa maiketsetso. Lingaka tsa fisiks tsa Amerika le Jeremane, lilemong tse mashome a mabeli a metso e meraro, li hlahloba masimo a motlakase a Lefatše, li ile tsa hlahisa phofo ea libinium ka lik'hilograma tse leshome le metso e mehlano ho feta Colombia. Ka lebaka leo, ho ile ha thehoa leru la lero la mali, le neng le e-na le sebōpeho se seholo se neng se le haufi le masimo a khoheli, e ileng ea etsa hore ho khonehe hore e fumane sebaka sa bona. Lilemo tse mashome a mabeli hamorao, li-binum particles le barium hydrogen sulphate tse fetotsoeng ka melapo li ile tsa sebelisoa ho ithuta polar aurora.

Joalokaha u ka bona ho tsohle tse boletsoeng ka holimo, barium hydroxide ke karolo ea bohlokoa haholo ho indasteri ea kajeno. Ntle le thepa e ikhethang, ho tla ba thata ho phetha mesebetsi e itseng. Hape ho ke ke ha lumeloa hore li-reagents tse entsoeng ka sebelisa hydroxide li sebelisoa ka mafolofolo makaleng 'ohle a moruo oa naha!
