Answer:
Pb(s), Fe(s) and Zn(s) will reduce to
Fe(s) and Zn(s) will reduce to
Explanation:
Standard reduction potential denotes ability to consume electrons from another species.
Hence, higher the standard reduction potential, higher will be the ability to oxidize another species.
Metal with value lower than 1.51 V will donate electron to
and thus reduces
to
.
So, Pb(s), Fe(s) and Zn(s) will reduce to
.
Metal with value lower than -0.40 V will donate electron to
and thus reduces
to
.
So, Fe(s) and Zn(s) will reduce to
.
