I-sodium bicarbonate, ifomula yemolekyuli yi-nahco₃, yindawo ye-inorganic ye-inorganic, i-rystalline ye-rystalline, akukho vumba, ityiwa, ilula ukuyinyibilika emanzini. Ukubola kancinci kancinci kwi-suby umoya okanye umoya oshushu, i-carbon diokside, kunye nobushushu ukuya kuthi ga kwi-270 ° C ngokupheleleyo ukubola ngokupheleleyo. Xa i-acidic, oko kukhembe kakhulu, kuvelisa ikharbon diokside.
I-sodium Bicarbonate isetyenziswa ngokubanzi ngokwemigaqo yohlalutyo lwe-chemistry, i-inorganic synthesis, imveliso yeshishini, yezolimo, yezolimo nemveliso yezilwanyana.
Iipropathi zomzimba:I-sodium bicarbonateNgaba i-crystal emhlophe, okanye iikristali ze-opaque monocliphal zikristali ezincinci, ezingeyiyo i-odor, ityiwa kancinci kwaye ipholile, kwaye i-vlycerin, i-ethanol e-ethanol. I-smollity emanzini yi-7.8G (18 ℃), i-16.0g (60 ℃), ukuxinana yi-2.20G i-2.20G yi-2.208, isalathiso se-Refreint yi-α: 1.465; β: 1.498; γ: 1.504, I-Entropy ye-24.4J / (MOLK), ivelisa ubushushu 229.3KJ / Mol, i-MOL, MOL) (22 ° C) .
Iipropathi zeekhemikhali:
I-1. I-acid kunye ne-alkaline
Isisombululo se-ACDEAROCOATATATATAL BICKALINALL BRORY ALKLIINE NGE-HYDROLYSIS: HCO3- + H2CO3CH2CH2CH2CH2CO3 + NO-EOHE-AHECEAUR OSCTURE Ixabiso le-ASTUREAREARMOOR MOBOS yi-8.3.
2. Dala nge-acid
I-Sodium Bicarbonate inokusabela nge-acid, njenge-sodium bicarbonate kunye ne-hydrochloride: nahco3 + hcl + cwaka + co2 h2o.
3. Ukuphendula kwiAlkali
I-sodium Bicarbonate inokusabela ngeAlkali. Umzekelo, i-sodium Bicarbonate kunye neSodium Hydroxide: Nahco3 + NaOH kunye ne-calcium ye-Calcium Hydroxide, ukuba isixa se-sodium sodium Bicarbonate sigcwele, kukho: i-2nahco3 + 2 = Caco3 + 2O; 2h2o;
Ukuba kukho inani elincinci le-sodium bicarbonate, kukho: Nahco3 + CA) 2 = Caco3 ↓ + Nah + h2o.
4. Impendulo kwityuwa
A. I-Sodium Bicarbonate inokuphinda kabini i-hydrolysis nge-alloride kunye ne-aluminium chloride, kwaye ivelise i-aluminium hydroxide, ityuwa yesodium kunye nekharbon diokbon diokbon.
I-3ahco3 + i-alcl3 = Al (oh) 3 ¶ + 3cl + 3co2 ↑; I-3ahco3 + i-al (Clo3) 3 = AL (O) 3 ¶ + 3abo3 ↑.
B. I-Sodium Bicarbonate inokusabela kwizisombululo zetyuwa ezithile zentsimbi, ezinje nge: 2hco3- + = MGC2 ↑ + MGCo3 ↑ + h2o.
I-5. Ukuhombisa ubushushu
Uhlobo lwe-sodium bicarbonate luzinzile kubushushu, kwaye kulula ukwahlukana. Ngokukhawuleza ukubola okungaphezulu kwe-50 ° C. NGE-270 ° C, i-carbon diokside ilahlekile ngokupheleleyo. Akukho lutshintsho kumoya owomileyo kwaye unciphise kancinci kwi-suble. I-Deation I-ECREATE YOKUGQIBELA
Intsimi yesicelo:
I-1. Ukusetyenziswa kwelebhu
I-sodium bicarbonateisetyenziswa njengokuhlalisa uhlalutyo kwaye ikwasetyenziselwa i-inorgasic synthesis. Ingasetyenziselwa ukulungiselela isodium ye-sodium ye-carbonate-sodium bicarbonate buffer isisombululo. Xa uyongeza isixa esincinci se-acid okanye i-alkali, inokugcina uxinzelelo lwe-hydrogen ngaphandle kotshintsho olubalulekileyo, olunokugcina ixabiso le-PH lizinzileyo.
I-2. Ukusetyenziswa kwemizi-mveliso
I-sodium Bicarbonate ingasetyenziselwa ukuvelisa izitshisi zomlilo kunye nokucima umlilo ze-foam, kunye ne-sodium Bicarbonate kwimveliso yerabha inokusetyenziselwa i-rubber kunye nemveliso yesiponji. I-Sodium Bicarbonate kumzi-mveliso we-metlilljeal inokusetyenziswa njengearhente yokunyibilika ngokuphosa i-shots yentsimbi. I-sodium Bicarbonate kwishishini lomatshini inokusetyenziswa njengomncedisi wobumba obanjiweyo (isandwich) sesanti. I-sodium Bicarbonate kwishishini lokuprinta kunye nokudayela lingasetyenziswa njengearhente yokulungisa umbala, i-Acid -ase-I-Buffer ye-Buffer, kunye ne-Deyer Deyer Deder kwi-Arhente yoNyango ePrinta; Ukongeza isoda ukuya kwidayini kunokubathintela i-gauze egameni. Uthintelo.
I-3. Ukusetyenziswa kokutya ukutya
Ukuqhubela ukutya, i-sodium Bicarbonate yeyona ndawo isetyenziswa kakhulu esetyenziselwa ukuvelisa iibhiskithi kunye nesonka. Umbala waphuzi-phandle. Yikharbon diokside kwisiselo sesoda; Inokudityaniswa nge-alm ukuya kwi-alkaline ye-alkaline evuthiweyo, okanye ingenziwa yi-citromes njengelitye loluntu iAlkali; Kodwa njengearhente yolondolozo lwebhotelo. Ingasetyenziselwa njengesiqhamo kunye nearhente yemifuno yemifuno kwimifuno. Ukongeza malunga ne-0.1% ukuya kwi-0,2% ye-sodium bicarbonate xa uhlamba iziqhamo kunye nemifuno inokuzinza eluhlaza. Xa i-sodium Bicarbonate isetyenziswa njengeziko leziqhamo kunye nearhente yonyango lwemifuno, inokunyusa ixabiso leziqhamo kunye nemifuno ngokupheka kweziqhamo kunye nemifuno, iphucule i-proting Iiseli zezicubu zokutya, kwaye zichithe amacandelo anomdla. Ukongeza, kukho ifuthe kubisi lwebhokhwe, kunye nexabiso le-0.001% ~ 0.002%.
I-4. Ezolimo kunye ne-Farry yezilwanyana
I-sodium bicarbonateIngasetyenziselwa ukuncipha kwezolimo, kwaye kunokwenza ukungabikho komxholo we-lysine ekutokothweni. I-sodium yesodium bicarbonate kwinani elincinci lamanzi okanye ukuxuba kwi-gxininise ukondla inyama yenkomo (inani elifanelekileyo) ukukhuthaza ukukhula kwenyama yenkomo. Inganyusa kakhulu ukuveliswa kobisi lweenkomo zobisi.
5. Ukusetyenziswa kwezonyango
I-sodium Bicarbonate inokusetyenziswa njengesixhobo esiyi-sub ye-chiermaceuticals, esetyenziselwa ukunyanga ityhefu ye-gurec acid, i-metabolic acid ityhefu, kwaye inakho kwakhona i-alkaline umchamo. Inganciphisa ityhefu yezintso ye-Sulno, kwaye kuthintele i-hemoglobin ekubeni ifakwe kwi-subular tulisa xa i-hemolysis, kwaye iphathe iimpawu ezibangelwa yi-gestric acid egqithisileyo; Inaliti ye-intravenous ayizo-itotific kwityhefu yeziyobisi. Intloko eqhubekayo, ilahleko yokutya, isicaphucaphu, ukugabha, njl.
Inqaku lokugcina kunye nezothutho: I-Sodium Bicarbonate yimveliso engaqhelekanga, kodwa ifanele ithintelwe kumswakama. Gcina kwitanki eyomileyo yomoya. Sukudibanisa ne-acid. Isoda yokubhaka esidleleni akufuneki idityaniswe nezinto ezinetyhefu ukukhusela ungcoliseko.
