Ammonium citrate yog dej-soluble ntsev nrog cov tshuaj lom neeg (NH4) 3C6h55o7. Nws yog siv nyob rau hauv ntau cov ntawv thov, los ntawm cov tshuaj, los ntawm cov tshuaj thiab kev lag luam khoom noj kom ntxuav thiab ua qhov pib ntawm kev tshuaj lom neeg tshuaj lom neeg. Ua ammonium citrine hauv tsev yog cov txheej txheem ncaj, tab sis nws yuav tsum tau txais kev tiv thaiv qee yam tshuaj thiab kev nyab xeeb nyab xeeb. Hauv no blog ncej, peb yuav tshawb txog cov kauj ruam los tsim cov ammonium citrate, cov khoom tsim nyog, thiab kev saib xyuas kev nyab xeeb.
Khoom siv xav tau
Ua ammonium citrate, koj yuav xav tau:
- Citric Acid (C6h8o7)
- Ammonium hydroxide (nh4oh), tseem hu ua aqueous ammonia
- Dej distilled
- Ib tug loj beaker lossis flask
- Ib tug pas nrig stirring
- Ib lub phaj kub lossis bunsen burner (rau cua sov)
- Ib lub ntsuas hluav taws xob (xaiv tau, tab sis yuav pab rau kev tswj hwm lub pH)
- Kev Nyab Xeeb Kev Nyab Xeeb
- Hnab looj tes
- Qhov chaw muaj cua zoo los yog lub hood fume
Kev Nyab Xeeb Ua Ntej
Ua ntej koj pib, nws yog ib qho tseem ceeb kom nco ntsoov tias ob qho tib si citric acid thiab ammonium hydroxide tuaj yeem tsim kev puas tsuaj yog tias tsis ua haujlwm zoo. Txhua zaus yuav tsum hnav cov kev nyab xeeb goggles thiab cov hnab looj tes, thiab ua haujlwm hauv qhov chaw muaj cua zoo lossis hauv qab cov duab qab zib kom tsis txhob nqus tau pa.
Cov txheej txheem
Kauj ruam 1: Npaj koj qhov chaw ua haujlwm
Teeb koj lub beaker lossis flask, nplawm cov pas nrig, thiab pheter '(yog siv) hauv qhov chaw nyab xeeb thiab ruaj khov. Nco ntsoov tias koj lub phaj kub lossis bunsen burner yog npaj rau kev siv thiab koj tau nkag mus rau cov dej distilled.
Kauj ruam 2: Ntsuas citric acid
Hnyav tawm qhov yuav tsum tau muaj ntawm citric acid. Qhov tseeb yuav yog nyob ntawm cov nplai ntawm koj cov khoom tsim, tab sis ib qho piv yog peb lub moles hydroxide rau txhua tus mole ntawm citric acid.
Kauj ruam 3: yaj citric acid
Ntxiv cov citric acid rau lub beaker lossis flask, ces ntxiv cov dej distilled kom yaj nws. Ua kom sov cov sib tov maj mam yog tias yuav tsum tau pab nrog kev sib cais. Cov dej yuav nyob ntawm lub ntim uas koj xav ua kom koj cov tshuaj kawg.
Kauj ruam 4: Ntxiv ammonium hydroxide
Maj mam ntxiv ammonium hydroxide rau cov citric acid daws thaum nplawm. Qhov kev tawm tsam ntawm citric acid thiab ammonium hydroxide yuav tsim ammonium citrate thiab dej raws li nram no:
Kauj ruam 5: Saib Xyuas Ph
Yog tias koj muaj lub xov tooj, saib xyuas lub ph ntawm cov kev daws teeb meem thaum koj ntxiv ammonium hydroxide. Tus p p yuav tsum sawv raws li cov tshuaj tiv thaiv zuj zus. Taw rau pH ib ncig 7 txog 8 los xyuas kom meej.
Kauj ruam 6: Txuas ntxiv nplawm
Khaws stirring qhov sib xyaw kom txog thaum lub citric acid tau ua kom sov thiab daws tau meej. Qhov no qhia tau tias ammonium citrate tau tsim.
Kauj Ruam 7: Cua txias thiab crystallization (yeem)
Yog tias koj xav tau txais cov ntawv crystalline ntawm ammonium citrate, tso cai daws kom maj mam. Cov muaju yuav pib tsim raws li cov tshuaj txias.
Kauj Ruam 8: Kev lim thiab ziab
Thaum cov tshuaj tiv thaiv tiav thiab cov kev daws teeb meem yog tseeb (lossis crystallized), koj tuaj yeem lim tawm cov khoom siv tsis muaj txiaj ntsig. Cov kua dej uas tseem tshuav lossis cov khoom siv crystalline yog ammonium citrate.
Kauj ruam 9: Cia
Khaws cov ammonium citrate nyob rau hauv lub airtight ntim, deb ntawm tshav kub thiab lub teeb los tswj nws ruaj khov.
Tag
Ua ammonium citring yog cov txheej txheem tshuaj yooj yim uas tuaj yeem ua tiav nrog cov khoom kuaj thiab tshuaj lom neeg. Nco ntsoov ua raws li cov kev nyab xeeb thaum ua haujlwm nrog tshuaj, thiab nco ntsoov nkag siab cov khoom ntawm cov tshuaj uas koj siv. Ammonium citrate, nrog nws cov kev siv ntau, yog qhov tseem ceeb kom nkag siab thiab muaj kev paub hauv thaj chaw ntawm Chemistry thiab dhau mus.
