I-ammonium citrateityuwa e-soluble yamanzi kunye ne-chemical formula (NH4) 3C6H5O7.Isetyenziswa kwizicelo ezahlukeneyo, ukusuka kumayeza kunye neshishini lokutya ukuya kwiimveliso zokucoca kwaye njengendawo yokuqala yokwenziwa kweekhemikhali.Ukwenza i-ammonium citrate ekhaya yinkqubo ecacileyo, kodwa ifuna ukufikelela kwiikhemikhali ezithile kunye nezilumkiso zokhuseleko.Kule post yebhlog, siza kuphonononga amanyathelo okuvelisa i-ammonium citrate, imathiriyeli efunekayo, kunye nokuqwalaselwa kokhuseleko.
Izinto Ezifunekayo
Ukwenza i-ammonium citrate, uya kufuna:
- I-Citric acid (C6H8O7)
- I-Ammonium hydroxide (NH4OH), eyaziwa ngokuba yi-ammonia enamanzi
- Mamanzi amisiwe
- Ibhekile enkulu okanye iflaski
- Intonga eshukumisayo
- Ipleyiti eshushu okanye isitshisi seBunsen (yokufudumeza)
- Imitha ye-pH (uyazikhethela, kodwa iluncedo kulawulo lwe-pH oluchanekileyo)
- Iiglasi zokhuseleko
- Iiglavu
- Indawo enomoya owaneleyo okanye ifume hood
Ukhuseleko kuqala
Ngaphambi kokuba uqale, kubalulekile ukuba uqaphele ukuba zombini i-citric acid kunye ne-ammonium hydroxide inokuba yingozi xa ingaphathwa kakuhle.Ngalo lonke ixesha unxibe iiglavu zokhuseleko kunye neeglavu, kwaye usebenze kwindawo engenamoya okanye phantsi kwesigqubuthelo somsi ukunqanda ukuphefumla umsi.
Inkqubo
Inyathelo 1: Lungisa indawo yakho yokusebenza
Misa ibhekile okanye iflaski yakho, intonga yokuxhokonxa, kunye nemitha ye-pH (ukuba uyayisebenzisa) kwindawo ekhuselekileyo nezinzileyo.Qinisekisa ukuba ipleyiti yakho eshushu okanye isitshisi seBunsen sikulungele ukusetyenziswa kwaye unofikelelo kumanzi adiliweyo.
Inyathelo lesi-2: Ukulinganisa i-Citric Acid
Ukulinganisa umlinganiselo ofunekayo we-citric acid.Isixa esichanekileyo siya kuxhomekeka kwisikali semveliso yakho, kodwa umlinganiselo oqhelekileyo ziimoles ezintathu ze-ammonium hydroxide kwimole enye ye-citric acid.
Inyathelo 3: Nciba iCitric Acid
Yongeza i-citric acid kwi-beaker okanye i-flask, uze ungeze amanzi adibeneyo ukuze uchithe.Fudumeza umxube ngobunono ukuba kuyimfuneko ukunceda ekunyibilikeni.Ubungakanani bamanzi buxhomekeke kumthamo onqwenela ukwenza isisombululo sakho sokugqibela.
Inyathelo lesi-4: Yongeza iAmmonium Hydroxide
Yongeza kancinane i-ammonium hydroxide kwisisombululo se-citric acid ngelixa uvuselela.Ukusabela phakathi kwe-citric acid kunye ne-ammonium hydroxide kuya kuvelisa i-ammonium citrate kunye namanzi ngolu hlobo lulandelayo:
Inyathelo lesi-5: Beka iliso kwi-pH
Ukuba unemitha ye-pH, jonga i-pH yesisombululo njengoko usongeza i-ammonium hydroxide.I-pH kufuneka inyuke njengoko i-reaction iqhubeka.Jonga i-pH malunga ne-7 ukuya kwi-8 ukuqinisekisa ukusabela okupheleleyo.
Inyathelo lesi-6: Qhubeka nokuvuselela
Qhubeka udibanisa umxube de i-citric acid iphendule ngokupheleleyo kwaye isisombululo siyacaca.Oku kubonisa ukuba i-ammonium citrate yenziwe.
Inyathelo 7: Ukupholisa kunye neCrystallization (Ngokuzikhethela)
Ukuba ufuna ukufumana i-crystalline form ye-ammonium citrate, vumela isisombululo ukuba sipholile ngokukhawuleza.Iikristale zinokuqalisa ukumila njengoko isisombululo siphola.
Inyathelo lesi-8: Ukuhluza kunye nokomisa
Emva kokuba impendulo igqityiwe kwaye isisombululo sicacile (okanye sigxininise), unokucoca nayiphi na into enganyibilikiyo.Ulwelo oluseleyo okanye oluqinileyo lwecrystalline yi-ammonium citrate.
Inyathelo 9: Ugcino
Gcina i-ammonium citrate kwisitya esingangeni moya, kude nobushushu kunye nokukhanya ukuze ugcine uzinzo.
Ukuqukumbela
Ukwenza i-ammonium citrate yinkqubo yekhemikhali elula enokufezwa ngezixhobo ezisisiseko zebhubhoratri kunye neekhemikhali.Ngalo lonke ixesha khumbula ukulandela imigaqo yokhuseleko xa usebenza ngemichiza, kwaye uqiniseke ukuba uyaziqonda iimpawu zezinto ozisebenzisayo.I-Ammonium citrate, kunye noluhlu lwayo olubanzi lwezicelo, iyikhompawundi ebalulekileyo ukuqonda kunye nolwazi kwintsimi yekhemistri nangaphaya.
