Barium hydroxide. Tinozivei nezvake?

Barium - ndiwo makemikari chinhu periodic table kuti zvaanoita nemvura uye asidhi mhinduro. Anoumba barium hydroxide vane nzira iri Ba (OH) 2 (chinyakare zita "caustic barite"). Uyu kunzwisisa inorganic fuma. Externally ine chimiro upfu chena, zvinosanganisira segirazi crystals. fuma Izvi zvikuru soluble mvura - uye tembiricha remvura riri kumusoro, ari solubility nani. "Barite mvura" (kana zvine barium hydroxide mhinduro) raireva kuti mvura iri unoparara Ba (OH) 2. Barium hydroxide vakasununguka zvaanoita pamwe carbon dioxide, uye naizvozvo ayo aqueous mhinduro (kana "barite mvura") rinoshandiswa mune Analytical kemisitiri sechinhu reagent nokuda CO2.

Uyezve, barite mvura inogona reagent kuti sulfate uye carbonate ions. Nemvura yakanaka solubility kuti barium hydroxide iri insoluble chose doro. Nyaya iyi iri zvinowanzoshandiswa sectors siyana hwenyika. Asi vasati kushandisa hydroxide, unofanira kudzidza pamusoro sei anogadzirwa kubva iripo reagents. Saka barium hydroxide inotengwa nevanhu Kuparadzwa mumvura inopisa kana muchidziisa oxide kuti barium sulfide mune norwizi chaipisa chiutsi. Izvi zvinogona kuwanika chete murabhoritari, sezvo muupenyu hwezuva nezuva, izvi hazvibviri kwete chete, asiwo ngozi utano hwevanhu.

Barium hydroxide rinoshandiswa kuti kubviswa sulfate ions kubva mhuka uye miriwo nemafuta, maindasitiri zvinogadzirisa, uyewo zvinoshandiswa kugadzira necesium uye rubidium hydroxide sezvo chimwe chezvinonhuwira mafuta.

Barium hydroxide ane ehupfumi siyana, kusanganisira alkali. Rinoshandiswa mumafuta indasitiri nokuita yokuvirisa mafuta. Uyezve, kwakadaro hydroxide kunoratidza zvakakwana rinozviti chirungiso kuti mafuta, saka zvino inobva kubudisa dzinoverengeka zvakafanana zvigadzirwa. Non-ferrous simbi uye kwemakemikari indasitiri kushandiswa barium hydroxide mumaindasitiri dzavo. Nevakawanda kushandiswa sezvo barium oxide hydrate reagent kuti SO42- uye CO32-, panguva kuchenesa kwemafuta mhuka uye miriwo nemafuta sezvo chikamu mafuta, kana achibvisa SO42- kubva maindasitiri mhinduro.

Kugadzirira Ba munyu uye hydroxides, Cs, Rb pamusoro sulfates dzavo kana carbonates haisi pasina kushandisa reagent akadai barium hydroxide. Nyaya iyi rave kuva inokosha kuona zvinogona kushandiswa hydroxide iri indasitiri. Zvinoshamisa, barium inoshandiswa kusika chakagadzirwa kometi: peya barium, izvo akasunungura muchikepe chitundumusere-musere, zvinoodza nyore ionize Mwaranzi yezuva uye dzikava rakajeka yeplasma gore.

At mashanu repfumbamwe rokubata rokupedzisira chemakore, apo Soviet interplanetary otomatiki chiteshi "Luna-1" anoita ayo kutiza, wokutanga chakagadzirwa kometi akasikwa. Physics America uye Germany muna manonwe, ichitsvaka remagetsi minda Pasi, akaita kusunungurwa barium upfu iri uwandu gumi makirogiramu chete pamusoro muColombia. Izvi zvakaguma yeplasma gore, waiva elongated chimiro, riri pamwe remagineti, zvichiita kuti tsanangurai nzvimbo yavo. Makore makumi maviri gare gare, kuti tudonhwe barium sulfate uye barium kutendeukira jets zvaishandiswa kudzidza ari Aurora.

Sezvaunogona kuona kubva zvose pamusoro apa, barium hydroxide iri raiva rokuti chinokosha indasitiri ano. Pasina kwayo yakasiyana ehupfumi zvichava zvakaoma kuita zvimwe basa. Nesuwo tinogona kugamuchira akasika apo kushandisa hydroxide reagents vari zvinowanzoshandiswa zvinenge sectors dzose upfumi!
