k) Would PbO2 oxidize H2O (at pH= 0)?
10) Use the redox table below to answer the following questions 2+ a. Would Mn02 reduce Cu? h) Would 02 oxidize Au (at pH-0)? b. Would Mn2 reduce Cu? i) Would O2 oxidize Au in the presence of Clions (at pH- 0)? 2+ c. Would MnO2 oxidize Cu? d. Would MnO2 oxidize Cu? 0 e. Would Mn02 oxidize Cu? i)Would O2 oxidize Pb? k) Would PbO2 oxidize H2O (at pH-0)? f. Would Cr3+ reduce Ni2*? Would Cr2 reduce Ni2*?
Solution
A) No MnO2 cannot reduce Cu 2+ ions. Because its SRP value is greater than copper ions.
B) Yes. Because SRP value of Mn +2 ions is less. So it can reduce it.
C) Yes. It can oxidize ( More SRP value of MnO2)
D) Yes. It can oxidize Cu +1 ions too.
E) Yes.
F) Yes it can reduce Ni +2 because oof less Srp value of Cr +3
G) yes.
H) No.
I) .....
J) No. It can\'t.
K)Yes.

Would Cr3+ reduce Ni2*? Would Cr2 reduce Ni2*?
Solution
A) No MnO2 cannot reduce Cu 2+
ions. Because its SRP value is greater than copper ions.
B) Yes. Because SRP value of Mn +2
ions is less. So it can reduce it.
2. C) Yes. It can oxidize ( More SRP value of MnO2)
D) Yes. It can oxidize Cu +1
ions too.
E) Yes.
F) Yes it can reduce Ni +2
because oof less Srp value of Cr +3
G) yes.
H) No.
I) .....
J) No. It can't.
K)Yes.
