Barium hydroxide. Abin da muka sani game da shi?

Barium - shi ne da wani sinadari a cikin lokaci-lokaci tebur cewa reacts da ruwa da kuma acid mafita. Yana Forms barium hydroxide wanda dabara ne Ba (OH) 2 (gargajiya sunan "caustic barite"). Wannan shi ne wani hadadden inorganic abu. Azahiri yana da wani nau'i na fararen foda, kunsha na m lu'ulu'u. Wannan abu ne mai matuƙar narkewa a cikin ruwa - da kuma yawan zafin jiki na ruwa ne mafi girma, mafi alhẽri solubility. "Barite ruwa" (ko wani cikakken barium hydroxide bayani) ake magana a cikin ruwa a wadda ake narkar Ba (OH) 2. Barium hydroxide da yardar kaina reacts tare da carbon dioxide, sabili da haka ta ruwa-ruwa bayani (ko "barite ruwa") da ake amfani a analytical sunadarai a matsayin reagent for CO2.

Bugu da ƙari kuma, barite ruwa zai iya zama a matsayin reagent zuwa sulfate da carbonate ions. Tare da kyau ruwa solubility na barium hydroxide ne gaba daya insoluble a barasa. Wannan yanayin da aka yi amfani da ko'ina a cikin daban-daban sassa na tattalin arziki. Amma kafin yin amfani da hydroxide, kana bukatar ka koyi game da yadda aka samar daga samuwa reagents. Saboda haka, barium hydroxide da aka samu ta hanyar rushe a ruwan zafi, ko kuma ta gasa oxide na barium sulfide a wani rafi da superheated tururi. Wannan za a iya cimma kawai a cikin dakin gwaje-gwaje, kamar yadda a cikin rayuwar yau da kullum, wannan tsari ne ba kawai ba zai yiwu ba, amma kuma kawo hadari ga lafiyar dan adam.

Barium hydroxide da ake amfani domin kau da sulfate ions daga dabbobi da kuma kayan lambu mai, masana'antu mafita, kazalika da amfani da shirya da cesium da rubidium hydroxide a matsayin man shafawa bangaren.

Barium hydroxide yana da daban-daban Properties, ciki har da Alkali. Ana amfani da a cikin masana'antun man fetur da yin man Additives. Haka kuma, irin wannan hydroxide daidai bayyana kanta a matsayin wani ƙari ga mai, don haka a yanzu shi dogara ne a kan samar da wani yawan irin kayayyakin. Non-ferrous metallurgy da kuma sinadaran masana'antu amfani da barium hydroxide a cikin masana'antu. Yadu yi amfani da matsayin barium oxide hydrate reagent zuwa SO42- da CO32-, a lokacin tsabtatawa na dabba fats da kuma kayan lambu mai kamar man shafawa bangaren, a lokacin da cire SO42- daga masana'antu mafita.

Shiri na Ba salts da hydroxides, Cs, RB na sulfates ko carbonates ba tare da yin amfani da irin wannan reagent kamar yadda barium hydroxide. Wannan yanayin ya kuma zama muhimman hakkokin a kayyade da yuwuwar amfani da hydroxide a cikin masana'antar. Abin mamaki, barium ake amfani da su haifar da wucin gadi tauraro mai wutsiya: a biyu daga barium, wanda aka saki a kan jirgin da kumbon sama jannati, ayan readily ionize rana ta haskoki da kuma juya a cikin wani haske jini girgije.

A hamsin da tara ta karshe Millennium, a lokacin da Soviet interplanetary atomatik tashar "Luna-1" da ke sa ta gudu, na farko wucin gadi tauraro mai wutsiya da aka halitta. Physics da Amurka da kuma Jamus a cikin seventies, binciko electromagnetic filayen su a duniya, sanya a saki barium foda a cikin adadin goma sha biyar kilo kawai sama Colombia. Wannan sa a cikin jini girgije, wanda yana da wani elongated siffar, an located tare da Magnetic filin, sa shi yiwuwa a saka su location. Shekaru ashirin da daga baya, da barbashi na barium sulfate da barium tuba zuwa ga jiragen sama da aka yi amfani da nazarin da Aurora.

Kamar yadda ka gani daga duk na sama, barium hydroxide ne quite wani muhimmin bangaren da zamani a masana'antu. Ba tare da ta musamman Properties zai zama quite wuya a gudanar da wani aiki. Mun kuma ba zai iya yarda da cewa halitta lokacin amfani da hydroxide reagents an yadu amfani a kusan dukkanin sassa na tattalin arzikin!
