Sodium Bicarbonate, molekuline ni NAHCO₃, ni ubwoko bwimvange

Sodium Bicarbonate, amata ya molekuline ni NAHCO₃ ， ni ifumbire mvaruganda, hamwe nifu ya kirisiti yera, nta mpumuro nziza, umunyu, byoroshye gushonga mumazi.Buhoro buhoro kubora mu kirere cyinshi cyangwa mu kirere gishyushye, bibyara dioxyde de carbone, kandi ubushyuhe bugera kuri 270 ° C burangirika rwose.Iyo ari acide, irabora cyane, itanga dioxyde de carbone.
Sodium bicarbonate ikoreshwa cyane mubijyanye no gusesengura chimie, synthesis organique, umusaruro winganda, umusaruro wubuhinzi nubworozi.

Imiterere yumubiri:sodium bicarbonateni kirisiti yera, cyangwa kristu ya monocliplative opaque ni kristu nkeya, ntabwo ari impumuro nziza, umunyu muke kandi ukonje, kandi byoroshye gushonga mumazi na glycerine, kandi ntibishobora gushonga muri Ethanol.Ubushyuhe bwo mumazi ni 7.8g (18 ℃), 16.0g (60 ℃), ubucucike ni 2,20g / cm3, igipimo ni 2.208, igipimo cyo kuvunika ni α: 1.465;β: 1.498;. .

Ibikoresho bya shimi:
1. Acide na alkaline
Igisubizo cyamazi ya sodium bicarbonate ni alkaline nkeya kubera hydrolysis: HCO3- + H2O⇌H2CO3 + OH-, 0.8% igisubizo cyamazi pH agaciro ni 8.3.
2. Koresha aside
Sodium bicarbonate irashobora kwitwara hamwe na aside, nka sodium bicarbonate na hydrochloride: nahco3 + HCL = NaCl + CO2 ↑ + H2O.
3. Igisubizo kuri alkali
Sodium bicarbonate irashobora kwitwara hamwe na alkali.Kurugero, sodium bicarbarbonate na sodium hydroxide reaction: nahco3 + naOh = Na2CO3 + H2O;na calcium hydroxide reaction, niba ingano ya sodium sodium bicarbonate yuzuye, hariho: 2NAHCO3 + CA (OH) 2 = CACO3 ↓ + NA2CO3 + 2H2O;
Niba hari bike bya sodium bicarbonate, hariho: Nahco3 + CA (OH) 2 = CACO3 ↓ + Naoh + H2O.
4. Kwitabira umunyu
A. Sodium bicarbonate irashobora gukuba kabiri hydrolysis hamwe na chloride ya aluminium na chloride ya aluminium, kandi ikabyara hydroxide ya aluminium, umunyu wa sodium na dioxyde de carbone.
3AHCO3 + AlCl3 = Al (OH) 3 ↓ + 3ACL + 3CO2 ↑;3AHCO3 + Al (CLO3) 3 = Al (OH) 3 ↓ + 3AClo3 + 3CO2 ↑.
B. Sodium bicarbonate irashobora kwitwara hamwe nigisubizo cyumunyu wicyuma, nka: 2HCO3- + Mg2 + = CO2 ↑ + MgCo3 ↓ + H2O.
5. Kubora kubushyuhe
Imiterere ya sodium bicarbonate ihagaze ku bushyuhe, kandi biroroshye kumeneka.Ihita ibora hejuru ya 50 ° C. Kuri 270 ° C, dioxyde de carbone irazimira rwose.Nta gihinduka mu kirere cyumye kandi kigenda kibora buhoro mu kirere cyuzuye.Kwangirika Ikigereranyo cya reaction: 2NAHCO3NA2CO3 + CO2 ↑ + H2O.

Umwanya wo gusaba:
1. Gukoresha laboratoire
Sodium bicarbonateikoreshwa nka analyse reagents kandi ikoreshwa no muburyo budasanzwe.Irashobora gukoreshwa mugutegura sodium karubone-sodium bicarbonate buffer igisubizo.Iyo wongeyeho aside nkeya cyangwa alkali, irashobora gutuma intumbero ya hydrogène ion idahinduka cyane, ishobora kugumana sisitemu pH agaciro gahamye.
2. Gukoresha inganda
Sodium bicarbonate irashobora gukoreshwa mu kuzimya umuriro wa pH hamwe no kuzimya umuriro, hamwe na sodium bicarbonate mu nganda za reberi irashobora gukoreshwa mu gukora reberi na sponge.Sodium bicarbonate mu nganda zibyuma birashobora gukoreshwa nkigikoresho cyo gushonga mu gutera ibyuma.Sodium bicarbonate mu nganda zubukanishi irashobora gukoreshwa nkumufasha wo kubumba umucanga (sandwiches).Sodium bicarbonate mu nganda zo gucapa no gusiga irangi zirashobora gukoreshwa nkibikoresho byo gutunganya amabara, aside -base ya bffer, hamwe nu muti wo gusiga irangi inyuma mugusiga irangi;kongeramo soda kurangi birashobora gukumira gaze muri gaze.Kwirinda.
3. Gukoresha ibiryo
Mugutunganya ibiryo, sodium bicarbonate nikintu gikoreshwa cyane mugutanga ibisuguti numugati.Ibara ni umuhondo -vanze.Ni dioxyde de carbone mu binyobwa bya soda;irashobora kwongerwaho na alum kugeza kuri alkaline ifu ya fermental, cyangwa irashobora kuba igizwe na citromes nkibuye rya gisivili alkali;ariko kandi nkumukozi wo kubungabunga amavuta.Irashobora gukoreshwa nkibara ryimbuto n'imboga mugutunganya imboga.Ongeraho hafi 0.1% kugeza 0.2% ya sodium bicarbonate mugihe cyoza imbuto n'imboga birashobora gutuza icyatsi.Iyo sodium bicarbonate ikoreshwa nkigikoresho cyo kuvura imbuto nimboga, irashobora kongera agaciro ka pH kimbuto n'imboga muguteka imbuto n'imboga, bishobora kongera agaciro ka pH k'imbuto n'imboga, kuzamura amazi ya proteyine, bigatera kworoha y'utugingo ngengabuzima twibiryo, no gushonga ibice bikurura.Mubyongeyeho, hari ingaruka kumata yihene, hamwe nogukoresha 0.001% ~ 0.002%.
4. Ubuhinzi n'ubworozi
Sodium bicarbonateirashobora gukoreshwa muguhunika ubuhinzi, kandi irashobora no kuzuza kubura ibinini bya lysine mubiryo.Sodium bicarbonate ya elegitoronike mu mazi make cyangwa ivanze muri concentrate kugirango igaburire inyama zinka (umubare ukwiye) kugirango iterambere ryinka ryiyongere.Irashobora kandi kongera umusaruro w'amata y'inka zitanga amata.
5. Gukoresha ubuvuzi
Sodium bicarbonate irashobora gukoreshwa nkibikoresho fatizo bya farumasi, ikoreshwa mukuvura aside gastricike ikabije, uburozi bwa aside metabolike, kandi ishobora no inkari za alkaline kugirango birinde amabuye ya aside irike.Irashobora kandi kugabanya uburozi bwimpyiko bwimiti ya sulfa, kandi ikabuza hemoglobine kudashyira mumyanya yimpyiko iyo ikabije hemolysis, ikanavura ibimenyetso biterwa na aside gastricike ikabije;gutera inshinge ntabwo ari umwihariko wo kwangiza ibiyobyabwenge Ingaruka zo kuvura.Gukomeza kubabara umutwe, kubura ubushake bwo kurya, isesemi, kuruka, nibindi

Inyandiko yo kubika no gutwara: Sodium bicarbonate nigicuruzwa kitari kibi, ariko kigomba gukumirwa.Bika mu kigega cyumye.Ntukavange na aside.Soda yo guteka iribwa ntigomba kuvangwa nibintu byuburozi kugirango wirinde umwanda.
