Sodium Bicarbonate. Zvishoma nezvishoma kupatsanura mumhepo yemhepo kana mweya unopisa, bayanidza carbon dioxide, uye kupisa kusvika 270 ° C zvachose yakagadziriswa zvachose. Kana iri acidic, yakakora yakarongeka, inogadzira kabhoni dioxide.
Sodium Bicarbonate inoshandiswa zvakanyanya maererano nekuongororwa kwemakemikari, inorganic synthesis, kugadzirwa kwemaindasitiri, kurima uye mhuka yekugadzira.
Zvivakwa zvemuviri:Sodium BicarbonateIchena chena, kana yeOpaque monuclative makristasi, zvisingamunhuhwirira, unonaka uye unotonhorera, uye unyoro mumvura negwencalin, uye kusakwana mu ethanol. Iyo Solubility mumvura ndeye 7.8G (18 ℃), β: 1.4498; γ: 1.504, standard entropy 24.4j / (moli k) .
Makemikari Zvivakwa:
1. Acid naAlkaline
Mhinduro yekumusoro yeSodium Bicarbonate ndeyekushaya simba nekuda kweHydrolysis: HCO3- + H2O⇌H2CO3 + O O OH- 0.8% Mvura mhinduro pH kukosha ndeye 8.3.
2. Ita neAcid
Sodium bicarbonate inogona kuita neAcid, yakadai seSodium Bicarbonate uye hydrochloride: nahco3 + HCL = CO2 ↑ + H2O.
3. Kuita kuAlkali
Sodium Bicarbonate inogona kuita naAlkali. Semuenzaniso, sodium bicarbarbonate uye sodium hydroxide reaction: nahco3 + naoh = na2co3 + h2o; uye Calcium Hydroxide Rections, kana huwandu hwe sodium sodium bicarbonate iri yakazara, kune: 2nahco3 + ca (OH) 2 = CACO3 ↓ + NA2CO3 + 2H2OO;
Kana paine chidiki chidiki cheSodium bicarbonate, kune: nahco3 + ca (OH) 2 = CACO3 ↓ + Naoh + h2o.
4. Kuita kune munyu
A. Sodium Bicarbonate inogona kaviri hydrolysis nealuminium chloride uye aluminium chloride, uye gadzira aluminium hydroxide, sodium munyu uye kabhoni dioxide.
3Ahco3 + alcl3 = al (o) 3 ↓ + 3Acl + 3co2 ↑; 3Ahco3 + Al (Clo3) 3 = Al (OH) 3 ↓ + 3Aclo3 + 3co2 ↑.
B. Sodium Bicarbonate inogona kuita neimwe simbi yematare mhinduro, yakadai se: 2hco3- + mg2 + = CO2 ↑ + mgco3 ↓ + H2O.
5. Kuora nekupisa
Chimiro cheSodium bicarbonate chakasimba pakudziya, uye zviri nyore kuputsa. Iyo yakakurumidza kuongororwa pamusoro pe50 ° C. na 270 ° C, kabhoni diokidhi yakarasika zvachose. Iko hakuna shanduko mumhepo yakaoma uye kupera zvishoma nezvishoma mumhepo yakanyorova. DeCucposition Iyo Reaction equation: 2nahco3na2co3 + CO2 ↑ + H2O.
Munda Unoshanda:
1. Rabhoritari kushandiswa
Sodium Bicarbonateinoshandiswa senzvimbo yekuongorora uye inoshandiswawo kune isorganic synthesis. Inogona kushandiswa kugadzirira sodium carbonate-sodium bicarbonate buffer solution. Paunenge uchiwedzera shoma ye acid kana alkali, inogona kuchengeta kusangana kwe hydrogen ion pasina shanduko dzakakosha, dzinogona kuchengetedza iyo ph kukosha ph kukosha kwakasimba.
2. Kushandiswa kwemaindasitiri
Sodium Bicarbonate inogona kushandiswa kubudisa phwira yemoto kudzima moto uye foam moto kudzima madzimba, uye sodium bicarbonate muindasitiri yerabha inogona kushandiswa kwerabha uye kuraswa. Sodium Bicarbonate muindasitiri yeSimbi inogona kushandiswa semumiriri wekunyungudika wekukanda mipendero yerudzi. Sodium Bicarbonate muindasitiri yemuchina inogona kushandiswa seyekuumbwa mubatsiri wekukanda simbi (sandwiches) jecha. Sodium Bicarbonate mukudhinda uye dhayeti indasitiri inogona kushandiswa seyakagadziriswa yemubatanidzwa, acid -base buffer, uye dhayi yemucheka kumashure kwekurapa mukudhinda. Kuwedzera soda kune dhayeziti kunogona kudzivirira gauze mune gauze. Kudzivirira.
3. Kugadziriswa kwekugadzirisa kushandiswa
Mukudya kwekudya, sodium bicarbonate ndiyo inonyanya kushandiswa yakashandiswa zvakasarudzika zvakasarudzika zvinoshandiswa kugadzira mabhisiketi nechingwa. Ruvara rwacho rugwaro rwellow -brown. Iyo kabhoni diaboni mudumbu rechando; Inogona kuumbwa nealum kuenda kuAlkaline yakarongedzwa hupfu, kana inogona kuumbwa neCitromes sewe Stone Alkali Alkali; asi zvakare sebhotoro rekuchengetedza mumiriri. Inogona kushandiswa semichero uye miriwo yekuvhara mumiririri mukugadzirisa kwemiriwo. Kuwedzera nezve 0,2% kusvika 0,2% yeSodium Bicarbonate Paunenge uchigeza michero nemiriwo inogona kusimbisa girini. Kana sodium bicarbonate inoshandiswa semichero uye yemiriwo kurapwa kwemumiriri, inogona kuwedzera iyo michero yemichero uye miriwo, inovandudza iyo miriwo yemvura yeProtein, inosimudzira kupfava yemasero ezvekudya zvechikafu, uye nyungudusa zvinhu zvechikepe. Uye zvakare, pane mhedzisiro yemukaka wembudzi, nehuwandu hwekushandiswa kwe 0.001% ~ 0.002%.
4. Zvekurima uye mhuka yemhuka
Sodium BicarbonateInogona kushandiswa pakurima kwekushaikwa, uye inogona zvakare kugadzira nekushaikwa kwerinini zvemukati mukudyisa. Solulable Sodium Bicarbonate mune imwe shoma yemvura kana inosanganisa mukuisa pfungwa yekupa nyama yemombe (mari yakakodzera) kusimudzira kukura kwembambo. Izvo zvinogona zvakare kuwedzera zvakanyanya kugadzirwa kwemukaka yemombe dzemukaka.
5. KUSHANDISA KUSHANDISA
Sodium Bicarbonate inogona kushandiswa seyakaisa zvinhu zveMishonga, iyo inoshandiswa kurapa yakawandisa gastric acid, metabolic acid yehupfu, uye inogona zvakare alkaline urine kudzivirira netari acid matombo. Inogona zvakare kuderedza iyo itsvo kutuka kwemishonga yemishonga, uye kudzivirira hemoglobin zvinodhaka, uye kudzivirira hemoglobin kubva kuShut Intravenus jekiseni haisiri-secarific kune inodhaka inodhaka yekubata kwekurapa. Kuenderera mberi musoro, kurasikirwa kwechido, kusvotwa, kurutsa, nezvimwe.
Kuchengetedza uye Chekufambisa Cherechedzo: Sodium Bicarbonate chisipo chigadzirwa, asi chinofanira kudzivirirwa kubva pakunyorova. Chengetedza mune yakaoma mhepo tangi. Usasanganisa neAcid. Inodakarira baking soda haifanirwe kusanganiswa nezvinhu zvine chepfu kuti udzivise kusvibiswa.
