Sodium bicarbonate, mawonekedwe amwambo ndi Nahco₃, ndi mankhwala onunkhira, okhala ndi ufa woyera, wopanda fungo, mchere, wosavuta kusungunuka m'madzi. Pang'onopang'ono kuwola mu mpweya kapena mpweya wotentha, amapanga mpweya woipa, ndikutentheza mpaka 270 c gar c wowola kwathunthu. Ikakhala acidic ikakhala yamphamvu, imapangidwa mwamphamvu, ndikupanga mpweya woipa.
Sodium Bicarbonate imagwiritsidwa ntchito kwambiri poyerekeza kusanthula kwamankhwala, synthesis synthesis, kupanga mafakitale, zopangidwa ndi nyama.
Katundu wathupi:sodium bicarbonateNdi makhiristo oyera, kapena okhwima monchocliplart amalira pang'ono, omwe si fungo, mchere pang'ono ndi ozizira, ndipo amasungunuka mosavuta m'madzi ndi glyceleble mu ethanol. Kusungunuka m'madzi ndi 7.8g (18G (18), 16.0g (60 ℃), kachulukidwe ndi 2.20g / cm3, njira yolowera ndi α: 1.465; Β: 1. 1.498; Γ: 1. 1.504, Equipy 24.4j / (Moel ·k / Mol, ndi Osungunula) 20.89j / (22 ° C) .
Mankhwala:
1. Acid ndi Alkaline
Madzi am'madzi a sodium bicarbonate ndi ofooka alkaline chifukwa cha hydrolysine: hco3- + HONO⇌H2C2Ch2Ceh2Coh2, 0,8% Madzi am'madzi ndi 8.3.
2. Chitani ndi acid
Sodium Bicarbonate akhoza kuchita ndi asidi, monga sodium bicarbonate ndi hydrochloride: nahco3 + hcl = Nacl + CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO.
3. Kuchita ndi alkali
Sodium Bicarbonate akhoza kuchita ndi alkali. Mwachitsanzo, sodium bicarbate ndi sodium hydroxide zomwe zimachitika: Nahco3 + Naoh = Na2co3 + h2o; Ndipo calcium hydroide, ngati kuchuluka kwa sodium bicarbonate yadzaza, pali: 2nahco3 + 2 = Caco3 2 = na2co3 + 2H2CO;
Ngati pali gawo laling'ono la sodium, kuli: Nahco3 + ca (o) 2 = Caco3 ↓ + Naoh + h2o + h2o + h2o + h2o.
4. Kuchita Mchere
A. Sodium Bicarbonate kawiri hydrolysis ndi aluminium chloride ndi aluminiyamu cloride, ndikupanga mchere wa hydroxide, mchere wa kaboni dayokisi.
3ahco3 + ALCL3 = AL (OH) 3 ↓, 3Aacl + 3co 3Co; 3ahco3 + AL (Clo3) 3 = AL (OH) 3 ↓, 3ACLLO3 + 3CO2 ↑
B. Sodium Bicarbonate akhoza kuchita zinthu zina zamchere zamchere, monga: 2hco3- + h2 ↑ ↑ ↓ ↓ ↓, h2o. + H2o.
5. Kugwedeza ndi kutentha
Mtundu wa sodium bicarbonate amakhala wokhazikika pa kutentha, ndipo ndikosavuta kuthyola. Amawola mwachangu kuposa 50 ° C. Pa 270 ° C, kaboni dayokisiyi yatayika kwathunthu. Palibe kusintha mu mpweya wouma ndikuwola pang'onopang'ono mpweya. Dongosolo la Dongosolo la Kulanda: 2nahco3na2co2co2co3co3CO3 CO2 ↑ ↑ On + H2O.
Gawo la ntchito:
1. Gwiritsani ntchito labotale
Sodium bicarbonateimagwiritsidwa ntchito ngati ma reagents owunikira ndipo imagwiritsidwanso ntchito kwa avorganial synthesis. Itha kugwiritsidwa ntchito kukonzekera sodium carbonate-sodium bicarbonate yankho la buffer. Mukawonjezera acid ochepa kapena alkali, imatha kusungabe mayodgen mayoji osasintha, omwe amatha kusunga mtengo wamtengo wapatali wa dongosolo.
2. Kugwiritsa ntchito mafakitale
Sodium Bicarbonate imatha kugwiritsidwa ntchito kupanga zozimitsa moto wa ma ph ndi zozimitsa moto, ndi sodium bicarbonate mu malonda ogulitsa mphira zitha kugwiritsidwa ntchito popanga mphira komanso spoonge. Sodium Bicarborbonate mu makampani azitsulo zitha kugwiritsidwa ntchito ngati wothandizira wosungunuka woponyera minyewa. Sodium bicarborbonate mu bizinesi yamakina itha kugwiritsidwa ntchito ngati wothandizira woumba wopanga michenga (masangweji). Sodium Bicarborbonate yosindikiza ndi utoto imatha kugwiritsidwa ntchito ngati mtundu wosinthira utoto, acid --Base buffer, ndi zopangira nsalu zakumbuyo wothandizira makina osindikizira; Kuonjezera koloko pa utoto kungalepheretse gauze mu gauze. Kupewa.
3. Kugwiritsa ntchito chakudya
Mu chakudya popanga, sodium bicarbonate imagwiritsidwa ntchito kwambiri yomwe imagwiritsidwa ntchito kupanga mabisiketi ndi mkate. Mtunduwo ndi wachikasu -. Ndi kaboni dayokisaidi mu zakumwa za soda; Itha kuphatikizidwa ndi alum kukhala alkaline yopanda ufa, kapena imatha kupangidwa ndi zigawo zamiyala ngati mwala wamiyala ya alkali; komanso monga wothandizira mankhwala otetezedwa. Itha kugwiritsidwa ntchito ngati zipatso ndi utoto wopangidwa ndi masamba mu masamba. Kuphatikiza pafupifupi 0.1% mpaka 0.2% ya sodium bicarbonate akatsuka zipatso ndi ndiwo zamasamba amatha kukhazikika. Pamene sodium bicarbonate imagwiritsidwa ntchito ngati chipatso chothandizira zipatso ndi masamba, zimatha kuwonjezera mtengo wa zipatso ndi ndiwo zamasamba, zomwe zingakulitse mtengo wa zipatso ndi mapuloteni amadzi, amalimbikitsa kufewetsa ya misempha yazakudya, ndikusungunula zinthu zotheka. Kuphatikiza apo, pali zotsatira za mkaka wa mbuzi, ndi kuchuluka kwa 0,001% ~ 0.002%.
4. Ulimi ndi utoto
Sodium bicarbonateitha kugwiritsidwa ntchito pophukira kwaulimi, ndipo zimatha kukhalanso chifukwa chosowa matenda am'madzi. Sodium sodium bicarbonate mu madzi ochepa kapena kusakaniza kulowa mu kudyetsa ng'ombe (kuchuluka) kuti akweze kukula kwa ng'ombe. Imathanso kupanga mkaka wa mkaka wa mkaka.
5. Kugwiritsa Ntchito Zachipatala
Sodium Bicarbonate akhoza kugwiritsidwa ntchito ngati zopangira za mankhwala am'mimba, omwe amagwiritsidwa ntchito pochiza kwambiri acid, kagayidwe kachakudya, komanso amathanso kukhala ndi mkodzo kuti ateteze miyala ya asidi. Zitha kuchepetsanso kuwopsa kwa impso kwa sulfabin chifukwa choyipitsidwa mu tul tul Tumor pomwe pachimake hemolysis, ndikuchiza zizindikiro zoyambitsidwa ndi m'mimba kwambiri; jakisoni wamkati sukhala -specific kuti athe kupha mankhwala othandizira. Kupitilira mutu, kuchepa kwa chakudya, nseru, kusanza, etc.
Dziwani Zosungira Sungani mu thanki yowuma. Osasakaniza acid. Kuphika koloko yophika sikuyenera kusakanikirana ndi zinthu zoopsa kuti mupewe kuipitsa.
