Barium hydroxide. Kodi tikudziwa za iye?

Barium - ndi chinthu mankhwala tebulo nthawi kuti wakwiya ndi njira madzi ndi acid. Ndipamene hydroxide barium amene ndiyo njira Ba (o) 2 (dzina chikhalidwe "caustic barite"). Izi ndi zovuta zochita kupanga mankhwala. Kunja ili mawonekedwe a ufa woyera, wopangidwa ndi timibulu mandala. mankhwala kwambiri sungunuka m'madzi - ndi kutentha kwa madzi ndi apamwamba, ndi solubility bwino. "Barite madzi" (kapena zimalimbikitsa barium hydroxide njira) anatchula madzi omwe uli kusungunuka Ba (o) 2. Barium hydroxide momasuka amachitira ndi carbon dioxide, choncho njira zake amadzimadzi (kapena "barite madzi") ntchito umagwirira mawunikidwe monga reagent kwa CO2.

Komanso, barite madzi atha kutumikira ngati reagent kuti sulphate ndi ayoni carbonate. Ndi madzi abwino solubility wa barium hydroxide ndi insoluble kwathunthu mowa. Mbali imeneyi chimagwiritsidwa ntchito zamanja zosiyanasiyana za chuma. Koma musanagwiritse ntchito hydroxide, muyenera kuphunzira za mmene amapangidwa kuchokera reagents zilipo. Choncho, barium hydroxide analandira ndi Kutha mu madzi otentha kapena Kutentha okusayidi wa barium sulfide mu mtsinje wa koopsa nthunzi. Izi chingapezeke yekha zasayansi, monga tsiku ndi tsiku, ndondomeko izi si zosatheka, komanso zoopsa thanzi la munthu.

Barium hydroxide ntchito kuchotsa ayoni sulphate kwa nyama ndi masamba mafuta, njira mafakitale komanso ntchito kukonzekera cesium ndi rubidium hydroxide ndi mbali lubricant.

Barium hydroxide ali katundu osiyana, kuphatikizapo soda. Izo ntchito makampani mafuta ndi kupanga zina mafuta. Komanso, hydroxide ngati mwangwiro kumaonekera monga zowonjezera kwa mafuta, kotero tsopano akuchokera kubala angapo mankhwala ofanana. zitsulo Non-akakhala ndi makampani mankhwala ntchito barium hydroxide m'mafakitale awo. Chimagwiritsidwa ntchito monga barium okusayidi hydrate reagent kuti SO42- ndi CO32-, pa yoyeretsa ya nyama mafuta ndi masamba mafuta monga lubricant chigawo, mukamafinya SO42- ku njira mafakitale.

Kukonzekera salt Ba ndi hydroxides, CS, RB wa sulfates awo kapena carbonates sakhala wopanda ntchito reagent monga barium hydroxide. Mbali imeneyi lilinso ofunika tipeze ntchito angathe hydroxide mu makampani. N'zosadabwitsa barium ntchito kulenga nyenyezi yokumba: nsapato barium, imatulutsidwa pa bolodi spacecraft, amakonda mosavuta ionize dzuŵa ndi kuwasandutsa yowala mtambo plasma.

Pa chaka makumi asanu ndi chinayi wa Zakachikwi otsiriza, pamene Soviet interplanetary basi siteshoni "Luna-1" zimapangitsa ndege ake, woyamba nyenyezi yokumba analengedwa. Physics America ndi Germany mu makumi asanu ndi awiri, ndipo akuyendayenda minda mu atomu ya Dziko Lapansi, anapanga amasulidwe barium ufa kuchuluka kwa makilogalamu khumi ndi asanu basi pamwamba Colombia. Chifukwa cha madzi mtambo, amene adali ndi mawonekedwe elongated, ili m'mbali munda maginito kukhala kotheka kuti musankhe malo awo. Patatha zaka makumi awiri, ndi particles wa barium sulphate ndi barium anatembenukira kwa Jets ankagwiritsa ntchito kuphunzira Aurora lapansi.

Monga mukuonera pa zonsezi pamwambapa, barium hydroxide si yofunika chigawo makampani ano. Popanda katundu wake wapadera kudzakhala kovuta kugwira ntchito zina. Ife simungakhoze kulandira adamlenga ntchito hydroxide ndi reagents ankagwiritsa ntchito pafupifupi m'magulu onse a chuma!
