The redox reactions into oxidation and reduction half reactions:-
Oxidation half reaction:
Zn → Zn2+ + 2e- (Loss of two electrons)
Reduction half reaction:
Cu2+ + 2e-→ Cu (Gain of two electrons)
Divide the following redox reactions into oxidation and reduction half reactions.
(i) Zn+Pb2→Zn2+Pb
(ii) Zn+Cu2+→Zn2+Cu
(iii) Cl2+2Br−→Br2+2Cl−
What is the oxidizing agent in the following redox reaction?
Zn(s)+Cu2+(aq)→Zn2+(aq)+Cu(s)
For cell reaction, Zn+Cu2+→Zn2++Cu, cell representation is
