Sodium hydroxide (naoh), bakunze kwita kuri Caustic Soda, soda ya Caustic, na yo yitwa Caustic Soda muri Hong Kong kubera irindi zina: Caustic Soda. Numushukanyi ukomeye mubushyuhe bwicyumba kandi ni BORROSTIVE CYANE. Byoroshye gushonga mumazi, igisubizo cyacyo kiratangaje ni alkaline kandi gishobora guhindura phenolphthalein. Sodium hydroxide nigice gikunze gukoreshwa kandi kimwe mumiti yingenzi muri laboratoire ya chimie. Sodium hydroxide ikurura byoroshye imyuka y'amazi mu kirere, bityo igomba gushyirwaho ikimenyetso kandi ikabikwa hamwe na reberi. Igisubizo cyacyo kirashobora gukoreshwa nkamazi yoza.
Ingaruka z'ibidukikije】
1. Ingaruka z'ubuzima. Inzira zitera: Guhumeka no kwinjizwa. Ibibazo byubuzima: Iki gicuruzwa kirababaza cyane kandi rukamba. Umukungugu cyangwa umwotsi urashobora kurakaza amaso n'imikorere y'ubuhumekero na corode septum ya septum; Guhuza neza hagati yuruhu n'amaso na Naoh bishobora gutera kuraka; Kwinginga impanuka birashobora gutera Gastrointestinal gutwika, mucous membranes isuri, kuva amaraso no guhungabana.
2. Ibidukikije nibiranga ibyago: Iki gicuruzwa ntikizaka. Bizabyara ubushyuhe bwinshi iyo guhura namazi n'amazi, bigize igisubizo cyangiza. Gutesha agaciro aside hamwe no kurekura ubushyuhe. Ruswa cyane. Ibicuruzwa (kubora) ibicuruzwa: birashobora gutanga imyotsi yangiza.
[Uburyo bwihutirwa bwo kwivuza]
1.. Gutangiza ibikorwa byihutirwa: Tandukanya agace kanduye kashe kandi ushireho ibimenyetso byo kuburira. Birasabwa ko ababakira bihutirwa bambara masike hamwe nikositimu yo gukingira imiti. Ntukajye mu buryo butaziguye ibikoresho byasohotse. Koresha amasuka meza kugirango uyikusanyirize mu kintu cyumye, gifite isuku kandi gitwikiriye. Ongeramo amafaranga make ya Naoh kumazi menshi, hindura kutabogama, hanyuma ubishyire muri sisitemu yo gutakaza amazi. Urashobora kandi koza amazi menshi hanyuma ugashyira amazi yakuweho muri sisitemu yo gutakaza amazi. Niba hari byinshi byo kumeneka, gukusanya no gutunganya cyangwa kujugunya nyuma yo kuvura.
2. Ingamba zo kurinda sisitemu yubuhushya kurinda: kwambara mask ya gaze mugihe bibaye ngombwa. Kurinda amaso: kwambara ibirahure byumutekano. Imyenda yo kurinda: Kwambara Rarera (bikozwe mubikoresho byo kurwanya ruswa). Kurinda intoki: Wambare gants ya reberi. Abandi: Nyuma yakazi, kwiyuhagira no guhindura imyenda. Witondere Isuku yawe. 3. Imfashanyo Yambere ingana uruhu: Koza ako kanya hamwe namazi menshi, hanyuma usabe 3% -5% Umuti wa Bariki. Guhuza amaso: guhita uzamura ijisho hanyuma uzunguruke amazi cyangwa umunyu byibuze byibuze iminota 15. Cyangwa kwoza hamwe na 3% yatimbi. Shakisha ubuvuzi. Guhumeka: kwimuka byihuse umwuka mwiza. Tanga guhumeka ibihimbano nibiba ngombwa. Shakisha ubuvuzi. Ingestion: Uburozi mu kanwa bigomba gukaraba vuba bishoboka hamwe na poroteyine, nk'amata, yogurt nibindi bicuruzwa byamata. Kwoza akanwa kahise mugihe umurwayi arimo akangutse, fata vinegere cyangwa umutobe windimu mu kanwa, kandi ushake ubuvuzi. Umuriro uzimya uburyo: Amazi y'ibigi, umucanga, dioxyde dioxyde ya edizide.
【Imiterere yimiti】
1. Naoh ni ishingiro rikomeye kandi rifite imitungo yose yibanze.
2. Umubare munini wa Oh- ionized mu gisubizo cy'amazebwe: Naoh = na + oh
3. Igisubizo na Acide: Naoh + HCL = Nacl + H2OONAO + HNO3 = nano3 + h2o
4. Irashobora kubyitwaramo hamwe na aside imwe: 2Naoh + So2 (adahagije) = na2so3 + 32SO3
5. Imyitwarire ya sodium hydroxide igisubizo na aluminium: 2al + 2h2o = 2h2o = 2No) ntabwo ari 2al + = 2h) = 2al (yewe ) 3 ↓ + 3H2 ↑)
6. ALKALI ALKLI irashobora gukoreshwa mugutegura alkali idakomeye: Naoh + nh4cl = nacl + nh3 · h2o
7. Irashobora kwitwara n'unyunyu
8. Naoh arabyangiza cyane kandi arashobora gusenya imiterere ya poroteyine.
9. Naoh ashobora gukuramo dioxyde de carbone. Inzira reaction ni izi zikurikira: 2Naoh + CO2 = na2co3 + H2O (umubare muto wa C2O + CO2)
10. Naoh ashobora kubyifatamo Silica, Sio2 + 2Naoh = Na2sio3 + H2O (kuko ahagarara ku kirahure Biragoye gufungura, mubisanzwe iyo amacupa yikirahure arimo sodium hydroxide, ibigarara bya reberi bigomba gukoreshwa)
11. Urashobora kubyitwaramo nibipimo. "Umutungo wa Alkali" uzahinduka umutuku iyo uhuye na FonolhthalethaLhthalein (HYDROSIM YANDITSWE.
12. Biroroshye guterera iyo shyirwa mu kirere, kandi bikurura CO2 mu kirere no kwangirika. Kubwibyo, bigomba gushyirwa mubidukikije byumye kandi birashobora no gukoreshwa mukabiri. 【Inyandiko】 gupakira neza kandi ukabika ahantu hakonje, humye. Ububiko butandukanye no gutwara aside hamwe nibikoresho byaka. Mugihe uruhu (ijisho) Twandikire, kwoza amazi menshi atemba. Niba ari uruhu, shyira aside ya boric nyuma. Niba yamizwe nikosa, ryoza umunwa n'amazi, unywe amata cyangwa igi. Ingamba zo kurwanya umuriro: amazi, umucanga. Abacuruzi bamwe ku isoko bakoresha sodium yamashanyarazi mugihe cyo gutunganya imyenda ikonje, bitemewe. Gukuraho umwambaro ntabwo bibogamye. CO2 ivanze muri gaze ya alkaline irashobora gukurwaho nibisubizo bikurikira: CO2 + 2NAOH = NA2CO3 + H2O. Calcium hydroxide nigice cyoroshye kandi ntishobora gukurura co2 mubihe bimwe, nuko naoh muri rusange akoreshwa mubukwe. Kwerekana CO2, Hydroxide ya Calcium irakoreshwa.
