Acid roj teeb them tawm thiab tawm hauv txoj cai
Qhov ob pob khoom ntawm cov roj teeb txhuas yog cov chemical hloov pauv mus rau hauv cov kua roj sulfuric kua qaub kom tsim hluav taws xob. Thaum DC siv (them), cov hlau lead oxide rau ntawm qhov zoo electrode phaj hloov mus rau xim av lead dioxide (PbO2), thiab cov hlau lead oxide ntawm daim phaj tsis zoo ua grey fleece txhuas (Pb, tseem hu ua sponge). txhuas). Thaum cov hmoov txhuas cia roj teeb tawm, cov khoom siv nquag ntawm cov paib zoo thiab tsis zoo nqus cov sulfuric acid thiab kev hloov pauv, thiab maj mam dhau los ua cov hlau lead sulfate (PbSO4). Thaum cov ntaub ntawv nquag rau ntawm daim phiaj zoo thiab tsis zoo los ua tib lub hmoov txhuas sulfate, qhov hluav taws xob ntawm lub roj teeb tawm kom tsis muaj qhov tawm mus. Txij ntawm no, lub roj teeb yuav tsum tau them rau lub zog ua kom nws rov qab los rau cov thawj coj cov roj carbon dioxide thiab cov hlau lead plaub, kom lub roj teeb txuas ntxiv mus.
