Lub cev muaj zog
Sulfuric acid (lwm kev sau ntawv sulfuric acid), tseem hu ua vitriol, yog cov ntxhia acid uas muaj cov ntsiab lus sulfur, oxygen thiab hydrogen, nrog cov mis molecular H2SO4. Nws yog cov tsis muaj xim, tsis muaj ntxhiab, thiab cov kua nplaum uas yog soluble hauv dej thiab yog synthesized hauv cov tshuaj tiv thaiv uas yog exothermic heev.
Nws cov corrosiveness tuaj yeem raug sau tseg rau nws qhov muaj zog acidic, thiab, yog tias nyob rau hauv qhov siab, nws lub cev qhuav dej thiab oxidizing zog. Nws tseem yog hygroscopic, yooj yim nqus dej vapor los ntawm huab cua.Thaum kev sib cuag, sulfuric acid tuaj yeem ua rau muaj tshuaj lom neeg kub hnyiab thiab txawm tias kub kub theem nrab; Nws yog qhov txaus ntshai heev txawm tias qis dua.
Sulfuric Acid concentrations yog siv rau ntau lub hom phiaj. Qee cov concentrations feem ntau yog:
| Loj feem H2SO4 |
Qhov ntom (kg / L) |
Nco ntsoov (mol / L) |
Hom npe |
| <29% | 1.00-1.25 | <4.2 | diluted sulfuric acid |
| 29-32 feem pua | 1.25-1.28 | 4.2-5.0 | roj teeb kua qaub (siv nyob rau hauv lead-acid roj teeb) |
| 62-70 feem pua | 1.52-1.60 | 9.6-11.5 | Chamber acid chiv acid |
| 78-80 feem pua | 1.70-1.73 | 13.5-14.0 | pej thuam acid Glover acid |
| 98.3% ua | 1.84 | 18.4 | concentrated sulfuric acid |
