In the following spontaneous reaction, the mercuric ion is:

Hg2+ + Cu → Hg + Cu2+

Question options:

a)

a stronger reducing agent than Cu2+

b)

It depends on the concentration of each species

c)

a weaker oxidizing agent than Cu2+

d)

a stronger oxidizing agent than Cu2+

e)

We can't tell without knowing the redox potentials

Based on the following reduction potential data, which is the strongest oxidizing agent?
red = +1.78 V for H2O2(aq) + 2H+(aq) + 2e- → 2H2O(l)


red = +0.800 V for Ag+(aq) + e- → Ag(s)
red = -0.130 V for Pb2+(aq) + 2e- → Pb(s)

Question options:

a)

Pb2+(aq)

b)

Ag+(aq)

c)

H2O2(aq)
