Sodiyumu Bicarbonate, formulala ya molecular ni nhco₃, ni ubwoko bwikirere kidasanzwe

Sodium bicarbonate, formulaire ya molekile ni nahco₃, ni urwangira inorungtike, hamwe n'ifu yera ya kirisiti, nta mpumuro, umunyu, byoroshye gusenya amazi. Buhoro buhoro kubora mu kirere cyangwa ikirere gishyushye, kibyara dioxyde de carbone, kandi ubushyuhe bugera kuri 270 ° C rwose. Iyo ari acide, iraboza cyane, itanga dioxyde de carbone.
Sodium Bicarbonate ikoreshwa cyane mubijyanye no gusesengura chimie, synthesis ya anornthesis, umusaruro winganda, umusaruro wunganda, umusaruro wubuhinzi nubwicanyi.

Ibintu byumubiri:sodium bicarbonateni kristu yera, cyangwa imyuka ya optaque ni kristu ntoya, atari impumuro, umunyu mu buryo buke, kandi byoroshye mumazi na ethan na ethanol. Kudakemura mumazi ni 7.8g (18,), 16.0g (60 ℃), ubucucike ni 2.20G / CM3, indangagaciro irose ni α: 1.465; A.: 1.498; γ: 1.504, entropy isanzwe 24.4J / (Mol · k), kubyara ubushyuhe 229.3KJ / Mol, ubushyuhe bushyushye 4. CP) 20.89J / (Mol · ° C) (22 ° C) .

Imiti yimiti:
1. Acide na alkaline
Igisubizo cyamazi ya sodium bicarbonate ni imbaraga za alkaline kubera hydrolysis: hco3- + h2oh2co3 + Oh-, 0.8% Ibisubizo bya PH agaciro ni 8.3.
2. Witondere ACID
Sodium Bicarbonate irashobora kubyitwaramo aside, nka sodium bicarbonate na hydrochloride: nahco3 + hcl = nacl + co2 ↑ + H2O.
3. Igisubizo kuri Alkali
Sodium Bicarbonate irashobora kubyitwaramo na Alkali. Kurugero, sodium bicarbate na sodium hydroxide reaction: nahco3 + naoh = na2co3 + h2o; Kandi reacroxide ya Calcium ya Calcium, niba umubare wa sodium wa sodium wuzuye wuzuye, hari: 2nahco3 + ca (oh) 2 = caco3 ↓ + na2co3 + 2h2o;
Niba hari umubare muto wa sodium bicarbonate, hari: nahco3 + ca (oh) 2 = caco3 ↓ + Naoh + H2O.
4. Igisubizo kumunyu
A. sodium bicarbonate irashobora gukuba kabiri hydlelyse hamwe na chloride ya aluminium hamwe na chloride ya aluminium, hanyuma ubyara Hydroxide, sodium umunyu na dioxyde de carbon.
3Ahco3 + Alcl3 = Al (OH) 3 ↓ + 3ACL + 3Co2 ↑; 3Ahco3 + al (Clo3) 3 = al (OH) 3 ↓ + 3AClo3 + 3Clo2 ↑.
B. Sodium Bicarbonate irashobora kwitwara hamwe nibisubizo byumunyu runaka, nka: 2hco3- + MG2 + = CO2 + = CO2 + = CO2 ↑ + MGCO3 ↓ + H2O.
5. Kwanduza kubushyuhe
Imiterere ya sodium bicarbonate irahagaze ku bushyuhe, kandi biroroshye gusenyuka. Itangira vuba hejuru ya 50 ° C. kuri 270 ° C, Dioxyde ya karubone irazimira rwose. Nta gihinduka mu kirere cyumye kandi kibora buhoro buhoro mu kirere. Kwangirika kugereranya: 2nahco3na2co3 + CO2 ↑ + H2O.

Umwanya wo gusaba:
1. Gukoresha Laboratoire
Sodium bicarbonateikoreshwa nkibisesengura kandi bikoreshwa kuri synthesis ya anorurnic. Irashobora gukoreshwa mugutegura karotium karubonate-sodium bicarbonate igisubizo buffer. Iyo wongeyeho aside imwe cyangwa alkali, irashobora kwibanda kuri sydrogan ion idafite impinduka zikomeye, zishobora kugumana sisitemu PH ihagaze neza.
2. Gukoresha inganda
Sodium Bicarbonate irashobora gukoreshwa mu gutanga Ph kuzimya umuriro hamwe no kuzimya umuriro ibyibushye, na sodium bicarbonate munganda za rubber zirashobora gukoreshwa kuri reberi na sponge. Sodiyumu Bicarbote munganda za Metallurgive zirashobora gukoreshwa nkumukozi ushonga wo guta ibyuma. Sodiyumu Bicarbote mubikorwa bya mashini birashobora gukoreshwa nkumufasha wo kugimbaza kuba imbata (sandwiches) umucanga. Sodiyumu Bicarbote mu nganda zo gucapa no gusiga irakoreshwa nkigiciro cyo gukosora amabara, acide -base buffer, hamwe ningoro yimyenda yinyuma yo gucapa; Ongeraho soda kugeza kurira birashobora kubuza gaze muri gaze. Gukumira.
3. Gukoresha ibiryo byo gutunganya ibiryo
Mu gutunganya ibiryo, sodium bicarbonate niyo yakoreshejwe cyane cyane umukozi utoroshye ikoreshwa mu gutanga ibisuguti numugati. Ibara ni umuhondo -rown. Ni dioxyde de carbone mubinyobwa soda; Irashobora kwiyongera hamwe na Alum muri Alkaline Ifu ya Alkaline isembuye, cyangwa irashobora kuba igizwe na citromes nkamabuye yabasivili alkali; Ariko kandi nk'umukozi ushinzwe kubungabunga amavuta. Irashobora gukoreshwa nkimbuto nimboga zifite amabara yo gutunganya imboga. Ongeraho hafi 0.1% kuri 0.2% ya sodium bicarbonate mugihe cyo gukaraba imbuto nimboga birashobora guhungabanya icyatsi. Iyo sodium bicarbonate ikoreshwa nkimbuto n'imboga zo kuvura imbuto, birashobora kongera agaciro k'amatungo n'imboga mu guteka imbuto n'imboga, kunoza amazi ya poroteyine, jyayo softening y'ibiribwa by'ibiryo, kandi bishonga ibice bya Areting. Byongeye kandi, hari ingaruka kumata yihene, hamwe nubunini bwo gukoresha 0.001% ~ 0.002%.
4. Ubuhinzi n'ubworozi
Sodium bicarbonateIrashobora gukoreshwa mugushira mubuhinzi, kandi irashobora kandi guhimba kubura ibintu bya Lysine mubiryo. Sodium sodium bicarbonate mumazi make cyangwa uvanze muburyo bwo kugaburira inyama zinka (amafaranga akwiye) kugirango uteze imbere ubwiyongere bwinka. Irashobora kandi kongera imbaraga amata yinka zamata.
5. Gukoresha Ubuvuzi
Sodiyumu Bicarbonate irashobora gukoreshwa nkibikoresho bibisi bya farumasi, bikoreshwa mugufata aside isake ikabije, uburozi bwa metabolic, kandi irashobora kandi inkari zo gukumira amabuye yingenzi. Irashobora kandi kugabanya uburozi bwibiyobyabwenge, kandi ibuza hemoglobine kubitsa muri renaltular tubular iyo ivurungano zikaze, kandi zifata ibimenyetso biterwa na aside isake ikabije; Intravenous intero ntabwo izwi cyane yo kwangiza ibiyobyabwenge. Gukomeza kubabara umutwe, gutakaza ubushake, isesemi, kuruka, nibindi.

Ububiko no gutwara abantu: Sodium Bicarbonate nigicuruzwa kitari cyiza, ariko bigomba gukumirwa nubushuhe. Ububiko mu kigega cyumye. Ntukavange na aside. Icyiciro cyo guteka soda ntigomba kuvangwa nibintu byuburozi kugirango wirinde umwanda.
