Yuav Ua Li Cas Hloov Ib Lub Pob Zeb Rau Hauv Cov Tooj Liab

Liab tooj liab, tseem hu ua liab tooj liab, yog tooj liab elemental, vim hais tias ntawm nws cov xim yog ntshav thiab lub npe, liab tooj liab yog muaj ntshiab tooj liab. Brass yog ib qho tooj liab alloy uas muaj tooj liab thiab zinc, uas tseem hu ua tooj dag zoo tib yam, thiab tseem muaj cov tooj liab alloy muaj li ntawm tooj liab thiab tin, uas yog hu ua tin bronze. Txhawm rau tig tooj dag rau hauv tooj liab liab, thawj zaug yog tshem tawm "zinc" hauv cov tooj liab alloy, qhov yooj yim tshaj plaws yog siv dilute hydrochloric acid kom yaj cov zinc, tus so yog liab tooj liab. Tab sis qhov no tsuas yog qhov saum npoo ntawm cov tooj dag block ua liab tooj liab. Lub "zinc" nyob rau hauv lub tooj dag alloy tseem muaj. Yog tias koj xav kom purify tooj dag, nws yuav tsum yog lub tuam txhab kev lag luam electrolysis thiab hlau smelting txoj kev
