Sodium Hydroxide (Naoh), inowanzozivikanwa seCousic Soda, Caustic Soda, inonzi Coodic Soda Iyo chena chena yakasimba pamhepo tembiricha uye inokanganisa zvakanyanya. Mvura inonyudza mumvura, mhinduro kwayo kwemvura ine simba rakasimba uye rinogona kutendeuka phenolphthalein red. Sodium hydroxide is a inowanzoshandiswa kwazvo base uye imwe yemishonga yakakosha mumakemikistry laborattal. Sodium hydroxide inobata nyore nyore mhepo mumhepo, saka inofanira kusungwa uye inochengeterwa nejira rabha. Kugadziriswa kwayo kunogona kushandiswa seyekushambidza mvura.
【Imamiriro ekunze】
1. Harts hazards. Invasion nzira: inhalation uye kumedza. Hutano Hwards: Ichi chigadzirwa chinotsamwisa uye chinonyanyisa. Guruva kana utsi hunogona kutsamwisa meso uye purakiti rekufema uye corrode the the nasal septum; Kusangana kwakananga pakati peganda nemaziso uye naNao kunogona kukonzera kupisa; Kupisa tsaona kunogona kukonzera gastrointestinal kupisa, mucous membrane kuwanda, kubuda ropa uye kuvhunduka.
2 Iyo ichaburitsa huwandu hombe rekupisa kana rakaratidzwa nemvura uye mupfu wemvura, kugadzira mhinduro yekukosheswa. Neutralals neakari uye kuburitsa kupisa. Zvakanyanyisa kukanganisa. Kuroverwa (Kuora) Zvigadzirwa: Mungave zvinokuvadza zvine muchetura zvine chepfu.
[Emergency kurapwa nzira]
1. Kubvisa mhinduro yekukurumidzira: Kuparadzanisa nzvimbo yakasvibiswa yakasvibiswa uye kumisikidza zviratidzo zvekunyevera zvakakomberedza. Zvinokurudzirwa kuti vanopindura vanopindura vanopfeka masks gasi uye masutu emakemikari anodzivirira. Usasangana zvakananga nezvinhu zvakaderedzwa. Shandisa foshoro yakachena kuti iiunganidze mune yakaoma, yakachena uye yakafukidzwa mudziyo. Wedzera shoma shoma yeNAHO iyo kune yakakura mvura, gadzirisa kuti iperekedze, uye wozoisa muganda remarara. Iwe unogona zvakare kugeza nemvura yakakura uye isa iyo yakakanyiwa geza mvura mune iyo marara system. Kana paine huwandu hukuru hweshuwa, unganidza uye kudzokorora kana kurasa kana kurasa mushure mekurapwa kusingakuvadzi.
2. Dziviriro yeziso: Pfeka magirazi ekuchengetedza emakemikari. Zvipfeko Zvekudzivirira: Pfeka Zvekare (zvakagadzirwa neAnti-Corrosion Zvigadzirwa). Dziviriro yeruoko: Pfeka magurovhosi rabha. Vamwe: Mushure mebasa, shawa uye shandura zvipfeko. Teerera kune Hutsanana. 3. Kubatsira kwekutanga kweganda kusangana: Rinse pakarepo nemvura yakawanda, wobva waisa 3% -5% boric acid mhinduro. Kubata ziso: pakarepo kusimudza eyelids uye flush nemvura inoyerera kana saline kwemaminetsi gumi nemashanu. Kana kugeza ne3% boric acid mhinduro. Tsvaga kurapwa. Inhalation: fambisa nekukurumidza kumhepo nyowani. Ipa kufema kwekufema kana zvichidikanwa. Tsvaga kurapwa. Kupinza: Toxins mumuromo inofanira kusukwa nekukurumidza sezvinobvira nechimwe chinhu senge protein, senge mukaka, yogurt uye zvimwe zvigadzirwa zvemukaka. Suka muromo wako ipapo kana murwere akamuka, tora vhiniga mhiniga kana mandimu nemuromo nemuromo, uye tsvaga kurapwa. Moto wekudzima moto: Mhezi mvura, jecha, kabhoni diokizi yemoto yekudzima moto.
【Chemical Properties】
1. Naoh isimba rakasimba uye rine zvese zvivakwa zvechigadziko.
2. Nhamba huru yeOpion iionised mumakwikwi mhinduro: Naoh = na + oh

4
5. Kuita kwesodium hydroxide solution uye aluminium: 2al + 2naoo = 2h2 ↑ (oh (aoh) naNao (naoh''h2o = (naoh) = 2L (OH ) 3 ↓ + 3h2 ↑)
6. A strong alkali can be used to prepare a weak alkali: NaOH + NH4Cl = NaCl + NH3·H2O
7. Unogona kuita neimwe salts: 2naoh + cuo4 = cu (OH) 2 ↓ + NA2So42nao
8. Nao inokoshesa zvakanyanya uye inogona kuparadza chimiro chemapuroteni.
9. Naoh inogona kutora carbon dioxide. Maitiro ezvekuita ari seanotevera: 2naoh + co2 = NA2co3 + H2OO (chiyero chidiki cheCo2) Naahco3 (nahco3 (yakawandisa CO2)
10 Zvakaoma kuvhura, saka kazhinji mabhodhoro emabhodhoro ane sodium hydroxide, anomira mambure anofanira kushandiswa)
11. Unogona kuita nezviratidzo. "Alkali Properties" ichavhunduka kana yakavhurwa phenolphthalelein
12. Zviri nyore kuita nemaune kana kuiswa mumhepo, uye kutora CO2 mumhepo uye unoshatirisa. Naizvozvo, inofanira kuiswa munzvimbo yakaoma uye inogona zvakare kushandiswa kune yakaoma gasi. 【Zvinyorwa】 rongedza zvakasimba uye chitoro munzvimbo inotonhorera, yakaoma. Kuparadzanisa nekuchengetera uye kufambisa kweAcids uye zvinopisa zvinhu. Kana iri yeganda (ziso) kusangana, geza nemvura yakawanda inoyerera. Kana iri ganda, shandisa boric acid mushure. Kana kumedzwa nekukanganisa, rinse muromo nemvura, chinwiwa mukaka kana zai chena. Matanho ekurwira moto: mvura, jecha. Vamwe vatengesi vari mumusika vanoshandisa maindasitiri sodium hydroxide paunenge uchigadzirisa shrimps, iyo isingatenderwi. Kubviswa kwekusarongeka hakuna kwaakarerekera. CO2 yakasanganiswa muAlkaline Gasi inogona kubviswa neinotevera Reaction: CO2 + 2naoh = N2CO3 + H2O. Calcium Hydroxide chinhu chinonyura zvishoma uye hachikwanisi kutora more co2 pasi pemamiriro akafanana, saka naOoh kazhinji inoshandiswa pakubata. Kuti aratidze CO2, calcium hydroxide inoshandiswa.
