Ammonium citrateyog dej-soluble ntsev nrog cov tshuaj formula (NH4) 3C6H5O7.Nws yog siv nyob rau hauv ntau daim ntawv thov, los ntawm kws tshuaj thiab cov khoom noj khoom haus kev lag luam mus rau tu cov khoom thiab raws li ib tug pib taw tes rau tshuaj synthesis.Ua ammonium citrate nyob rau hauv tsev yog ib qho yooj yim txheej txheem, tab sis nws yuav tsum tau nkag mus rau qee yam tshuaj thiab kev ceev faj txog kev nyab xeeb.Hauv tsab ntawv blog no, peb yuav tshawb xyuas cov kauj ruam los tsim cov ammonium citrate, cov ntaub ntawv tsim nyog, thiab kev xav txog kev nyab xeeb.
Cov ntaub ntawv xav tau
Txhawm rau ua kom ammonium citrate, koj yuav xav tau:
- Citric acid (C6H8O7)
- Ammonium hydroxide (NH4OH), tseem hu ua aqueous ammonia
- Cov dej distilled
- Ib tug loj beaker los yog lub hwj
- Ib tug stirring qws
- Lub phaj kub los yog Bunsen burner (rau cua sov)
- Lub pH meter (yeem, tab sis muaj txiaj ntsig rau kev tswj pH meej)
- looj tsom iav dub
- Hnab looj tes
- Ib qhov chaw zoo-ventilated los yog fume hood
Kev nyab xeeb ua ntej
Ua ntej koj pib, nws tseem ceeb heev uas yuav tsum nco ntsoov tias ob qho tib si citric acid thiab ammonium hydroxide tuaj yeem tsim kev puas tsuaj yog tias tsis ua haujlwm zoo.Yuav tsum hnav looj tsom iav dub thiab hnab looj tes, thiab ua haujlwm hauv qhov chaw muaj cua zoo lossis hauv qab lub hood kom tsis txhob nqus pa.
Txheej txheem
Kauj Ruam 1: Npaj Koj Qhov Chaw Ua Haujlwm
Teem koj lub beaker lossis lub hwj, nplawm pas nrig, thiab pH meter (yog siv) nyob rau hauv qhov chaw nyab xeeb thiab ruaj khov.Xyuas kom tseeb tias koj lub phaj kub los yog Bunsen burner yog npaj siv thiab koj muaj kev nkag tau rau cov dej distilled.
Kauj Ruam 2: Ntsuas Citric Acid
Ntsuas qhov xav tau ntawm citric acid.Tus nqi pes tsawg yuav nyob ntawm qhov ntsuas ntawm koj qhov ntau lawm, tab sis ib qho piv txwv yog peb moles ntawm ammonium hydroxide rau txhua txhua mole ntawm citric acid.
Kauj Ruam 3: Dissolve Citric Acid
Ntxiv citric acid rau hauv lub khob los yog lub hwj, ces ntxiv dej distilled kom yaj nws.Tshav qhov sib tov maj mam yog tias xav tau los pab nrog kev sib cais.Tus nqi ntawm cov dej yuav nyob ntawm qhov ntim koj xav ua kom koj qhov kev daws teeb meem kawg.
Kauj Ruam 4: Ntxiv Ammonium Hydroxide
Maj mam ntxiv ammonium hydroxide rau citric acid tov thaum nplawm.Cov tshuaj tiv thaiv ntawm citric acid thiab ammonium hydroxide yuav tsim ammonium citrate thiab dej raws li hauv qab no:
Kauj Ruam 5: Saib xyuas pH
Yog tias koj muaj pH meter, saib xyuas pH ntawm cov tshuaj thaum koj ntxiv ammonium hydroxide.Cov pH yuav tsum nce siab thaum cov tshuaj tiv thaiv nce ntxiv.Npaj rau pH nyob ib ncig ntawm 7 mus rau 8 kom paub meej cov tshuaj tiv thaiv.
Kauj ruam 6: Txuas ntxiv stirring
Khaws cov tshuaj sib tov kom txog thaum lub citric acid tau ua kom tag nrho thiab cov tshuaj ua kom pom tseeb.Qhov no qhia tias ammonium citrate tau tsim.
Kauj Ruam 7: Txias thiab Crystallization (yeem)
Yog tias koj xav tau ib daim ntawv crystalline ntawm ammonium citrate, cia cov tshuaj kom txias maj mam.Crystals yuav pib tsim thaum cov tshuaj txias.
Kauj Ruam 8: Lim thiab ziab
Thaum cov tshuaj tiv thaiv tiav thiab kev daws teeb meem yog qhov tseeb (lossis crystallized), koj tuaj yeem lim tawm cov khoom siv tsis tau.Cov kua lossis crystalline cov khoom seem yog ammonium citrate.
Kauj Ruam 9: Cia
Khaws cov ammonium citrate rau hauv lub thawv airtight, kom deb ntawm tshav kub thiab lub teeb kom nws ruaj khov.
Xaus
Kev ua ammonium citrate yog cov txheej txheem tshuaj lom neeg yooj yim uas tuaj yeem ua tiav nrog cov khoom siv hauv chav kuaj thiab tshuaj.Nco ntsoov ua raws li cov txheej txheem kev nyab xeeb thaum ua haujlwm nrog cov tshuaj, thiab nco ntsoov nkag siab txog cov khoom ntawm cov tshuaj uas koj siv.Ammonium citrate, nrog rau nws cov kev siv ntau yam, yog ib qho tseem ceeb sib xyaw kom nkag siab thiab muaj kev paub txog hauv thaj chaw ntawm chemistry thiab tshaj.
