Kipp lub apparatus: ib tug yooj yim ntaus ntawv rau lub thoob dej yug ntses

Kipp apparatus yog ib tug ntaus ntawv uas tso cai rau kom tau txais cov roj cua. Nws yog dav siv nyob rau hauv ib tug ntau yam ntawm laboratory kev ntsuam xyuas, thiab lub chaw soj nstuam, chemists xum siv thooj voos kheej kheej raws li cov roj qhov twg los. Nws yog ntau yooj yim thiab kev ruaj ntseg, raws li nyob rau hauv cov ntaub ntawv ntawm kev siv ntawm lub tshuab Kipp ntawm zus tau tej cov hydrogen thiab combustible gases yog qhov yuav tshwm ntawm explosions.

Yuav ua li cas yog nws ua hauj lwm?

Kipp lub apparatus ua hauj lwm nyob rau hauv ib tug yooj yim lub tswvyim, rau Piv txwv li, yog tias koj xav tau hydrogen. Tom qab ntawm qhov nruab nrab loj ntawm lub tank yog muab tso rau lattice nrog zinc granules. Nws yog poured mus rau hauv hydrochloric acid los yog sulfuric acid. Yog hais tias lub valve rau lub raj, lub escaping gases yog kaw, cov acid yuav nyob rau hauv lub qaum hopper thiab lub qis tank. Thaum qhib lub kais acid pib ntws los ntawm lub funnel thiab nyob rau sab ntawm lub thib ob tank. Cov tshuaj tiv thaiv nrog lub zinc yuav siv sij hawm muab cov evolution ntawm hydrogen. Qhov no yog feem ntau nqa tawm nyob rau hauv Science News for KIDS chav kawm ntawv. Tom qab qhov kawg ntawm qhov xyaum ua tej tus kais yog kaw, ntsig txog, hydrogen yog tsis tawm los ntawm qhov apparatus.

Yuav ua li cas nws muaj?

Niaj hnub nimno tshuab Kipp - ob sib npaug zos volume reservoir nrog ib lub hnab yas lub raj uas nkag mus rau hauv lub caj dab ntawm lub raj mis. Nws ob sab nruj nreem kaw yas lub kaus mom, uas saib kuas ceev ceev. Lub sab qaum kev ib lub raj yog txawm peem rau nrog ib tug Glued haum, los ntawm kev uas muaj peev xwm yuav tawm carbon dioxide. Txawm qis raj muaj ib tug stopper rau lub raj mis, thiab tus ceev ceev yog tiav vim lub fact tias siv tshwj xeeb nplhaib ntawm roj hmab los yog silicone. Nyob rau hauv lub Cork tau ua ib tug cutout qhov twg lub chalk los yog limestone yog loaded. Yuav kom acid thiab cov tshuaj zoo tham raj perforated qhov muab ib tug hu dawb cov ntaub ntawv. Lwm raj dua los ntawm ob leeg, uas yuav tsum tau nyob rau hauv thiaj li yuav neutralize acid vapors nyob rau hauv lub tso pa.

Yuav ua li cas kom tau cov pa roj carbon dioxide?

Heev feem ntau siv Kipp apparatus mus muab _CO2. raws li zoo raws li rau cov pa roj carbon dioxide. Rau lub hom phiaj no, cia li chalk thiab acetic acid. Mel muaj yuav rau hauv daim ntawv ntawm daim, tsis muaj plua plav. Tus ntaus ntawv yuav tsum tau sau nrog ib tug tsis muaj zog acetic acid tov, nws yog loaded rau hauv lub raj los ntawm saum toj no cwj mem av dawb, tom qab uas lub raj nws tus kheej yog tso rau hauv lub raj mis. Txij li thaum CO ₂ yog tso tawm nws yog rho los ntawm cov tes tsho, tom qab uas kis tau los ntawm ib tug dej qab zib kua thiab yog noj mus rau hauv lub tank. Thaum lub qhov hluav taws xob raj yuav tsum muab tso rau uas tsis yog-rov qab valve. Hais tias yog, tus Kipp apparatus yog operable tujtaws muaj ib tug tsis tu ncua roj siab, uas yog nyob ntawm cov lwm yam nyob rau ntawm qhov tob ntawm immersion rau hauv lub tank sprayer.

Qhov twg yuav nrhiav tau?

Muaj ntau craftsmen xav kom dhos rau no unit nrog koj ob txhais tes, qhov ntau hais tias qhov no yog tsis yog li ntawd tsis yooj yim li no mas. Nyob rau tib lub sij hawm, ib tug tshwj xeeb apparatus Kipp muag nyob rau hauv khw muag khoom noj rau lub thoob dej yug ntses, los ntawm kev uas cov pa roj carbon dioxide yog ua thiab khaws cia nyob rau hauv ib tug siab theem tau. Cov yooj yim heev qauv ntawm lub ntaus ntawv muaj xws li ob lub raj nrog nozzles, siab gauge, koob Unidirectional thiab acrylic raj.

Cov nqi ndlwg ntawm cov tshuaj cov tshuaj tiv thaiv yuav yog nyob ntawm seb yuav ua li cas npaum li cas calcium yog muaj nyob rau hauv chalk los yog limestone, nws ceev thiab porosity. Nws yog yog li ntawd thawj tsim nyog los tos ib tug me me npaum li cas ntawm cov dej hauv lub acid concentration: gas yuav tsum tau tso tawm nyob rau hauv ib tug me me npaum li cas, tab sis lub Churning los yog foaming yuav tsum tsis txhob yuav. Yog hais tias qhov tshuaj tiv thaiv yog qeeb thiab txoj cai npaum li cas ntawm cov roj yog tsis ua, nws yog tsim nyog los tsim kho lub tsev thiab siv ib tug loj ntim ntawm lub raj mis. Tab sis lub concentration ntawm acid yog tsis tsim nyog los ua rau kom, raws li nws muaj peev xwm yog li ntawd ib yam nkaus thiab sai sai neutralized.

Nyob rau hauv dav dav, lub ntaus ntawv yog pheej yig, raws li reagents nyob rau hauv daim ntawv ntawm cov cwj mem av dawb thiab acid yog heev pheej yig. Yog, thiab tus dais no yog heev yooj yim. Cov teeb meem nkaus xwb tej zaum yuav tshwm sim nrog lub rooj sib txoos - nws yog tsim nyog los nqa tawm zoo zoo thiab kom huv si nyob rau hauv thiaj li yuav ua tau cia siab rau thiab ceev ceev ntawm tus txha.
