Kev txhais ntawm concentrated sulfuric acid
Concentrated sulfuric acid, feem ntau hu ua dej tsis zoo, nrog cov tshuaj lom neeg cov tshuaj H₂SO₄, yog cov muaj zog ntxhia kua qaub nrog qhov siab corrosivity. Concentrated sulfuric acid hais txog cov tshuaj sulfuric acid nrog qhov loj feem ntau tshaj los sis sib npaug li 70%. Concentrated sulfuric acid kuj tseem corrosive: nyob rau hauv lub siab, kub siab sulfuric acid tuaj yeem corrode txhua cov hlau tshwj tsis yog iridium thiab ruthenium (txawm suav nrog kub thiab platinum), thiab cov xov tooj ntawm cov hlau uas tuaj yeem corroded txawm ntau tshaj li aqua regia. Sulfuric acid muaj qhov muaj zog oxidizing ntawm cov cuab yeej ntawm siab siab, uas yog ib qho kev sib txawv loj tshaj plaws ntawm nws thiab dilute sulfuric acid. Nyob rau tib lub sijhawm, nws tseem muaj lub cev qhuav dej, ua tsis yooj yim, acidity, nqus dej, thiab lwm yam.
