Yog li ntawd, cov electrolyte siv rau electroplating ib tsab xov xwm nrog nyiaj yog Sodium argentocyanide tov uas qhia kev xaiv C raws li kev xaiv raug. Lus Cim: Nyob rau hauv cov txheej txheem ntawm cov nyiaj plating cov khoom los yog ib qho tshuaj ntsuam xyuas uas yuav tsum tau plated yog tsim los ntawm cathode ntawm ib qho electrolytic cell.
Yuav ua li cas electrolyte yog siv thaum electroplating?
Ib aqueous tov ntawm nickel sulphate uas muaj nickel ions Ni2+ yog siv hauv electroplating.
Yuav ua li cas electrolyte yog siv thaum electroplating nyiaj ntawm hlau diav?
Vim li no, AgNO3 nyiaj nitrate yog siv los ua cov electrolyte rau electroplate nyiaj rau hauv ib diav.
Cathode twg siv rau electroplating nrog nyiaj?
(i) Cathode: Cov kab lus huv heev xws li tooj liab khob. Anode: Ib lub phaj lossis pas nrig ntawm nyiaj. (ii) Sodium argento cyanide (Na[Ag(CN)2]) thiab hydrocyaruc acid (HCN).
Cov electrolyte twg yog siv thaum lub sij hawm electroplating ntawm ib tsab xov xwm los ntawm nickel?
Nickel electroplating yog txheej txheem uas nyias txheej ntawm npib tsib xee electroplated rau ntawm cov hlau. Hauv cov txheej txheem no nickel sulfateyog siv los ua electrolyte, ib tsab xov xwm yuav tsum tau electroplated yog muab tso rau ntawm cathode thiab ib qho thaiv ntawm nickel hlau yog siv los ua anode.
