Chemistry ntawm cov roj teeb

Qhov sib npaug yog raws li nram no:

Tag nrho cov tshuaj tiv thaiv: Pb(s){{0}}PbO2(s)+2H2SO4(aq) Reversible symbol 2PbSO4(s)+2H2O(l)

Thaum tso tawm: Pb(s)-2e-+SO42-(aq) = PbSO4(s)

Positive PbO2(s){{5}}2e-+SO42-(aq)+4H+(aq)=PbSO4(s)+2H2O(l)

Total Pb(s){{0}}PbO2(s)+2H2SO4(aq)=2PbSO4(s)+2H2O(l)

Thaum them nyiaj electrolytic cell

Cathode PbSO4(s){{3}}2e-=Pb(s)+SO42-(aq)

Anode PbSO4(s){{6}}2H2O(l)-2e-=Pbo2(s){{9}}SO42-(aq)+4H+(a

Nco tseg (cathode thaum them tsis zoo thaum tso tawm)
