Kusukela emgudwini thola ukuma kwenhlayiya yeshubhu lokuhlola lamakhemikhali. Khombisa imiphumela ngefomethi ehlukaniswe ngamakhoma.
Context:Amapayipi okuhlola enzelwe imisebenzi ejwayelekile yamakhemikhali ngokuvamile enziwa ngengilazi, ngenxa yokumelana kwayo nokushisa. Amapayipi enziwe ngengilazi emelana nokwanda, ikakhulukazi ingilazi ye-borosilicate noma i-quartz encibilikisiwe, angamelana namazinga okushisa aphezulu afinyelela emakhulwini ambalwa ama-degree Celsius. Amapayipi e-chemistry ayatholakala ngobude nobubanzi obuningi, ngokuvamile kusuka ku-10 kuye ku-20 mm ububanzi no-50 kuye ku-200 mm ubude. Phezulu kuvame ukuba nomlomo ovuthayo ukusiza ukuthulula okuqukethwe. Amanye amashubhu okuhlola enziwa ukuba amukele isivalo seglasi esigaywe noma isivalo sesikulufa. Imvamisa zinikezwa ngengilazi encane encibilikisiwe noma indawo emhlophe ecwebezelayo eduze phezulu ukuze kubhalwe ngepensela. Amapayipi okuhlola asetshenziswa kabanzi ngamakhemikhali ukuphatha amakhemikhali, ikakhulukazi ekuhlolweni kwekhwalithi nasekuhloleni. Izingxenye zawo ezingaphansi eziyindilinga nezinhlangothi eziqondile zinciphisa ukulahleka kobukhulu lapho kuthelwa, zenza kube lula ukuzigeza, futhi zivumela ukuqapha okulula kokuqukethwe. Umphimbo omude, omncane weshubhu lokuhlola wehlisa ukusakazeka kwamagesi endaweni ezungezile. Amashubhu okuhlola ayiziqukathi ezifanele zokushisa inani elincane lezinto eziwuketshezi noma eziqinile ngesishisi seBunsen noma isishisi sotshwala. Umbhobho uvame ukubanjwa entanyeni yawo ngesibambo noma ngezipikili. Ngokuthambekisa ishubhu, phansi kungashiswa kuze kufike emakhulwini ama-degree elangabini, kuyilapho intamo ihlala ipholile, mhlawumbe ivumela umusi ukuba ugcwale ezindongeni zawo. Ishubhu elibilayo liyisivivinyo esikhulu esihloselwe ngokukhethekile ukubilisa uketshezi. Isivivinyo esiboshwe ngamanzi bese siphendulwa sibe yindebe egcwele amanzi sivame ukusetshenziselwa ukubamba amagesi, isibonelo ekuboniseni i-electrolysis. Isivivinyo esiboshwe ngesivalo sivame ukusetshenziselwa ukugcina okwesikhashana amasampula amakhemikhali noma ama-biological.
phansi okuyisicaba, okuyisiyingi, phansi okuyisigaxa
