Sodium bicarbonate, ifomula yama-molecular i-nahco₃, iyingxenye ye-inorgallic, ene-white crystalline powder, akukho phunga, onosawoti, okulula ukuncibilikisa emanzini. Kancane kancane ukubola emoyeni onomswakama noma umoya oshisayo, khiqiza i-carbon dioxide, futhi ukushisa kuze kufike ku-270 ° C okubolile ngokuphelele. Lapho i-acidic, ibolile kakhulu, ikhiqiza i-carbon dioxide.
I-Sodium Bicarbonate isetshenziswa kabanzi ngokuya ngokuhlaziywa kwamakhemikhali, ukukhiqizwa kwe-inorganic, ukukhiqizwa kwezimboni, ukukhiqizwa komlimi wezolimo kanye nezilwane.
Izakhiwo ezibonakalayo:sodium bicarbonateIkristalu emhlophe, noma amakristalu e-opaque monocliplive amakristalu amakristalu anamakhaza, okungelona iphunga, elinosawoti kancane futhi apholile, futhi ancibilikisa kalula emanzini kanye ne-glycerin, futhi ancibilike e-ethanol. I-solubity emanzini ingu-7.8G (18 ℃), 16.0g (60 ℃), ubuningi ngu-2.20g / cm3, inani le-2.208, inkomba eyedlulayo iyi-α: 1.465; β: 1.498; γ: 1.504, I-Entropy ejwayelekile 24.4j / (Mol · k), ikhiqize ukushisa 229.3kj / Mol, ukushisa okuncibilikisiwe 4.33kj / (CP) 20.89j / (22 ° C) (22 ° C) (22 ° C) (22 ° C) (22 ° C) (22 ° C) .
Izakhiwo zamakhemikhali:
1. I-acid ne-alkaline
Isixazululo esinamanzi se-sodium bicarbonate sibuthakathaka i-alkaline ye-alkaline ngenxa ye-hydrolysis: I-HCO3- + H2O⇌h2Co3 + Oh-, 0.8% I-ACCED ACCED HOLKO SALLUSE COLUSE NGAMA-8.3.
2. I-ACCE nge-acid
I-Sodium Bicarbonate ingasabela nge-acid, njenge-sodium bicarbonate ne-hydrochloride: nahco3 + hcl = i-NACL + CO2 ↑ + H2O.
3. Ukusabela ku-Alkali
I-sodium bicarbonate ingasabela nge-alkali. Isibonelo, ukusabela kwe-sodium bicarbarbonate kanye ne-sodium hydroxide Reaction: Nahco3 + Naoh = NA2CO3 + H2O; futhi ukusabela kwe-calcium hydroxide, uma inani le-sodium sodium bicarbonate ligcwele, kukhona: 2nahco3 + ca (oh) 2 = Caco3 ↓ + NA2CO3 + 2h2o;
Uma kunenani elincane le-sodium bicarbonate, kukhona: nahco3 + ca (oh) 2 = CACO3 ↓ + Naoh + H2O.
4. Ukuphendula usawoti
A. I-Sodium Bicarbonate ingakwazi ukuphinda i-hydrolysis ephindwe kabili nge-aluminium chloride ne-aluminium chloride, futhi ukhiqize i-aluminium hydroxide, usawoti we-sodium kanye nekhabhoni diokdide.
3AHo3 + alcl3 = al (oh) 3 ↓ + 3UCL + 3CO2 ↑; 3AHo3 + Al (Clo3) 3 = Al (oh) 3 ↓ + 3OCLO3 + 3CO2 ↑.
B. Sodium Bicarbonate ingasabela ngezixazululo ezithile zensimbi zensimbi, ezinjengokuthi: 2hco3- + MG2 + = CO2 ↑ + MGCO3 ↓ + H2O.
5. Ukubola ngokushisa
Uhlobo lwe-sodium bicarbonate luzinzile ekushiseni, futhi kulula ukubhidliza. Kuboshwe ngokushesha ngenhla kwe-50 ° C. ku-270 ° C, i-carbon dioxide ilahlekile ngokuphelele. Akukho shintsho emoyeni owomile futhi uqubuke kancane kancane emoyeni onomswakama. Ukubola ku-equation reaction equation: 2nahco3na2co2 + CO2 ↑ + H2O.
Inkambu Yesicelo:
1. Ukusetshenziswa kwelebhu
Sodium bicarbonateisetshenziswa njenge-reagents ehlaziya futhi isetshenziselwa futhi ukuhlanganiswa kwe-ingorganic. Ingasetshenziswa ukulungiselela isixazululo se-sodium carbonate-sodium bicarbonate buffer solution. Lapho ungeza inani elincane le-acid noma i-alkali, lingagcina ukugcwaliseka kwama-hydrogen ion ngaphandle kwezinguquko ezibalulekile, ezingagcina i-System Ph Inani elizinzile.
2. Ukusetshenziswa Kwezimboni
I-Sodium Bicarbonate ingasetshenziselwa ukukhiqiza ukukhiqiza izicishamlilo zomlilo kanye nezicishamlilo zomlilo we-foam, kanye ne-sodium bicarbonate embonini yerabha zingasetshenziselwa ukukhiqizwa kwerabha kanye nesiponji. I-Sodium Bicarbonate embonini ye-metallurgical ingasetshenziswa njenge-ejenti yokuncibilika yokuphosa ama-ingots ensimbi. I-Sodium Bicarbonate embonini yemishini ingasetshenziswa njengomsizi wokubumba we-cast yensimbi (sandwich) sand. I-Sodium Bicarbonate embonini yokuphrinta nokudaya ingasetshenziswa njenge-ejenti yokulungiswa kombala, i-acid -base buffer, nendwangu edaya ngemuva kokwelashwa kwangemuva kokuphrinta kokubala; Ukungeza i-soda kudaya kungavimba i-gauze ku-gauze. Ukuvimbela.
3. Ukusetshenziswa kokudla kokudla
Ekusebenzeni kokudla, i-sodium bicarbonate yi-ejenti esetshenziswa kakhulu esetshenziswa ukukhiqiza amabhisikidi nesinkwa. Umbala uphuzi-aphuzi. Kuyi-carbon dioxide esiphuzweni sosawoti; kungahlanganiswa nge-alum ku-alkalined powder evuthayo, noma kungakhiwa ama-citromes njengetshe lamatshe omphakathi; Kepha futhi njenge-ejenti yokulondolozwa kwebhotela. Ingasetshenziswa njenge-ejenti yezithelo ne-agent yemifino yemifino. Ukungeza cishe i-0.1% kuya ku-0.2% ye-sodium bicarbonate lapho ukugeza izithelo nemifino kungazinza luhlaza. Lapho i-sodium bicarbonate isetshenziswa njenge-ejenti yokwelashwa kwezithelo nokwelashwa kwemifino, ingakhulisa inani le-PH yezithelo nemifino ngokupheka izithelo nemifino, elingezelela inani lamaprotheni ezithelo, likhulise ukuthambisa amaseli wezicubu zokudla, bese uncibilikisa izakhi zezinkanyezi. Ngaphezu kwalokho, kunomthelela obisini lwembuzi, ngenani lokusetshenziswa kwe-0.001% ~ 0.002%.
4. Ezolimo kanye nokulimazeka kwezilwane
Sodium bicarbonateIngasetshenziselwa ukugcotshwa kwezolimo, futhi nakho kungenza ukuntuleka kokuqukethwe kwe-lysine kokuphakelayo. I-Soluble Sodium Bicarbonate ngenani elincane lamanzi noma ukuxubana emcabangweni wokugxila ukondla inyama yenkomo (inani elifanele) ukukhuthaza ukukhula kwenkomo. Kungandise kakhulu ukukhiqizwa kobisi kwezinkomo zobisi.
5. Ukusetshenziswa Kwezokwelapha
I-Sodium Bicarbonate ingasetshenziswa njengento eluhlaza yezemithi, esetshenziselwa ukwelapha i-gastric acid, futhi futhi ingaba umchamo we-alkaline ukuvikela amatshe e-uric acid. Kunganciphisa futhi ubuthi bezinso zezidakamizwa ze-sulfa, futhi bavimbele i-hemoglobin ekufakweni kokufaka ama-tubular revur lapho i-hemlysis ebukhali, futhi baphathe izimpawu ezibangelwa i-gastric acid; Umjovo we-intravenous akwenzi-aspecific ukufaka ubuthi bezobuthi umphumela wokwelashwa. Ukuqhubeka kwekhanda, ukulahleka kwesifiso sokudla, isicanucanu, ukugabha, njll.
Inothi lokugcina kanye nezokuhamba: I-Sodium Bicarbonate ngumkhiqizo ongeyena -dange, kepha kufanele ivinjelwe kumswakama. Gcina ethangini lomoya elomile. Ungahlanganisi ne-acid. I-BICK BINKO SODA akufanele ihlanganiswe nezinto ezinobuthi ukuvikela ukungcoliswa.
