yuav ua li cas ua hydrogen chloride
1. Yuav npaj HCl li cas hauv chav kuaj?
Muaj ob txoj hauv kev los npaj HCl hauv chav kuaj:
Chlorine reacts nrog hydrogen:
Cl2 + H2 → 2HCl
Hydrochloride reacts nrog muaj zog acids:
NaCl + H2SO4 → HCl + NaHSO4
Ammonium chloride reacts nrog sodium hydroxide:
NH4Cl + NaOH → NaCl + NH3 + H2O
2. Qhov twg yog hydrogen chloride tsim?
Hydrogen chloride muaj nyob rau hauv qhov chaw xws li volcanic eruptions, seawater evaporation, thiab av qeeg faults. Industrially, hydrogen chloride yog tsim los ntawm cov txheej txheem chlor-alkali.
3. Vim li cas HCl yog cov kua qaub tshaj plaws?
HCl yog cov kua qaub uas muaj zog tshaj plaws vim tias nws ua tiav ionizes, tsim cov hydrogen ions ntau. Hydrogen ions yog cov ntsiab lus ntawm cov kua qaub thiab txiav txim siab nws lub zog.
4. Dab tsi yog qhov kev siv ntau tshaj ntawm HCl?
Cov khoom siv tshuaj lom neeg: siv los ua cov tshuaj chlorides, hydrochlorides, organic compounds, thiab lwm yam.
Cov khoom siv raw: siv hauv metallurgy, electroplating, luam ntawv, papermaking, thiab lwm yam.
Cov khoom siv niaj hnub: siv los ntxuav, tshuaj tua kab mob, tshuaj dawb, thiab lwm yam.
5. Dab tsi yog qhov phom sij ntawm HCl?
Corrosiveness: HCl yog cov kua qaub uas muaj zog corrosive rau ntawm daim tawv nqaij, qhov muag, thiab ua pa.
Irritation: HCl muaj kev cuam tshuam rau tib neeg lub cev thiab tuaj yeem ua rau cov tsos mob xws li hnoos, mob hauv siab, thiab ua pa nyuaj.
Carcinogenicity: HCl yog suav tias yog carcinogenic.
6. Vim li cas HCl siv hauv tshuaj?
HCl yog siv rau hauv cov tshuaj, feem ntau yog rau kev kho mob ntawm hyperacidity, esophageal reflux thiab lwm yam kab mob.
7. Yuav ua li cas npaj HCl los ntawm ntsev?
Dissolve cov ntsev hauv dej, thiab tom qab ntawd ntxiv cov kua qaub uas muaj zog xws li sulfuric acid los yog hydrochloric acid kom hydrolyze hydrochloride.
NaCl + H2SO4 → HCl + NaHSO4
Cov ntsev yog yaj nyob rau hauv dej, thiab ces chlorine gas yog nkag mus rau chlorinate ntsev.
NaCl + Cl2 → NaCl + HCl
