Qhia: Cov txheej txheem txo nws tus kheej yog cov txheej txheem kev lag luam dav siv ntawm cov hlau rho tawm los ntawm cov zaub mov lossis cov ore tshwj xeeb tshaj yog rau cov hlau tsis tshua muaj electropositive xws li tooj liab (Cu), lead (Pb), mercury (Hg) thiab lwm yam.
Cov hlau twg yog rho tawm los ntawm electrolytic txo?
Peb hais Aluminium yog muab rho tawm los ntawm txoj kev txo electrolytic. Hauv txoj kev electro-refining, cov hlau tsis huv yog coj los ua anode thiab cov hlau ntshiab yog ua los ntawm cathode. Cov electrodes yog muab tso rau hauv acidified aqueous tov ntawm hlau ntsev los yog molten hlau ntsev.
Zn rho tawm los ntawm tus kheej txo?
Zinc tuaj yeem muab rho tawm los ntawm txo tus kheej. II. Ib qho kev nyuaj siab tiv thaiv qee yam ntawm cov khoom tuaj rau hauv froth.
Qhov twg ntawm cov hlau hauv qab no tsis tuaj yeem tau txais los ntawm kev txo qis cov tshuaj tiv thaiv?
Cov txheej txheem ntawm autoreduction yog siv nyob rau hauv metallurgy ntawm tsawg electropositive hlau xws li Hg, Pb, Cu thiab lwm yam. Li no, Feua electropositive ntau, tsis tau los ntawm nws pib txo.
Nws yog siv los txo cov alumina?
Vim Magnesium oxide's kab nyob hauv qab Aluminium, Magnesium tuaj yeem txo qis Alumina. Cov lus teb yog li no: Magnesium.
