Barium Hydroxide [Ba(OH)₂ & Ba(OH)₂·8H₂O]- Likopo le Litšebeliso
Barium Hydroxide, e fumanehang ka mefuta ea eona e sa keneleng metsi le e octahydrate, ke alkali e feto-fetohang le e arabelang e nang le thuso ea bohlokoa makaleng a indasteri, a laboratori le a tlhahiso ea lik'hemik'hale. Motheo oa eona o matla le ts'ebetso e ikhethang ea li-anion tse kang sulfate le carbonate li etsa hore e be sesebelisoa sa bohlokoa sa ts'ebetso le selelekela sa lik'hemik'hale.
Likopo tsa mantlha le Liindasteri:
1. Ts'ebetso ea Lik'hemik'hale le Selelekela sa Liindasteri
Barium Hydroxide e sebetsa e le thepa ea motheo ea ho qala tlhahiso ea mefuta e mengata ea metsoako e meng ea barium.
* Matsoai a Barium: Ke thepa ea mantlha e tala bakeng sa ho etsa matsoai a fapaneng a barium, ho kenyeletsoa barium chloride, barium nitrate le barium stearate.
* Ho kopanya lintho tse phelang: E sebelisoa haholo tlhahisong ea metsoako ea lintho tse phelang e thehiloeng ho barium, e sebetsang e le li-catalyst kapa li-stabilizer indastering ea polasetiki le rabara.
2. Moemeli oa Ts'ebetso ea Indasteri le Kalafo
Litšobotsi tsa eona tsa lik'hemik'hale li sebelisoa bakeng sa tlhoekiso, ho lokisa le ho lokisa lintho tse kotsi lits'ebetsong tse ngata.
* Phekolo le ho Nolofatsa Metsi: E tlosa li-anion tsa sulfate le carbonate ka katleho melapong ea metsi libakeng tsa indasteri, e thibela ho thehoa ha sekala ka har'a liboiler le litsamaisong tsa ho pholisa.
* Moemeli oa ho Fokotsa Metsi: Mofuta oa monohydrate o sebetsa hantle haholo ho ntšeng metsi a mangata a tlhaho le ho tlosa metsi a sa hlokahaleng lihlahisoa.
* Ho Hloekisa Tsoekere: E sebelisoa ts'ebetsong ea ho hloekisa tsoekere ho tlosa litšila.
* Indasteri ea Mafura le Oli: E sebetsa e le sesebelisoa sa ho lokisa le ho fetola oli ea liphoofolo le ea meroho bakeng sa tlhahiso ea mafura.
3. Khemistri ea Laboratori le ea Tlhahlobo
Laboratoring, Barium Hydroxide e ananeloa ka lebaka la bokhoni ba eona bo nepahetseng ba tlhahlobo.
* Titration ea Li-acid tse Fokolang: Matla a eona a motheo a matla a e etsa hore e be sesebelisoa se setle sa ho fokotsa li-acid tse fokolang, haholo-holo li-acid tsa organic, e leng se fanang ka pheletso e bohale.
* Sesebediswa sa ho lokisa khabone (CO₂): Se sebediswa e le sesebediswa se utlwahalang ho lemoha le ho monya CO₂, kaha se bopa barium carbonate e sa qhibiliheng.
4. Ditshebediso tsa Tlhahiso le Ditlatsetso
* Khalase le Liseramiki: Ke tlatsetso tlhahisong ea mefuta e itseng ea likhalase le li-glaze tsa seramiki, e ntlafatsang khanya le ho tšoarella.
* Rabara ea Maiketsetso: E sebetsa e le sesebelisoa sa ho qhibilihisa rabara ea maiketsetso, e ntlafatsang thepa ea eona ea mechini.
* Libolaya-dikokwanyana le Dithibela-mafu: Karolo ea bohlokoa tlhahisong ea likokoanyana tse itseng tse bolaeang dikokwanyana le lithibela-mafu tsa indasteri.

Litšobotsi tsa Bohlokoa le Melemo:
* Ho Sebetsa Haholo: E sebetsa hantle e le motheo o matla le moemeli oa ho hotetsa bakeng sa li-anion tse itseng.
* Selelekela se Feto-fetohang: Sejo sa bohlokoa bakeng sa metsoako e meng e mengata ea barium.
* Mefuta e Mengata: E fumaneha e le Anhydrous, Monohydrate, le Octahydrate ho latela ditlhoko tse itseng tsa tshebetso (mohlala, octahydrate hangata e kgethwa ka lebaka la ho sebetsana le yona le dibopeho tsa ho qhibiliha ha yona).
Tlhokomeliso: Tlhahisoleseding e hlahisitsoeng ke ea merero e hlalosang. Metsoako ea Barium e tlameha ho sebetsoa ka mehato e loketseng ea ts'ireletso. Ke boikarabello ba mosebelisi ho netefatsa mekhoa e sireletsehileng ea ho sebetsana le sehlahisoa le ho fumana hore na se loketse ts'ebeliso ea sona e ikhethileng ho latela melao eohle ea lehae, ea mmuso le ea federal.
