According to the standard reduction potentials:   `Pb^(2+)(aq) + 2e^(-) rightarrow Pb(s)` `E^(@) = -0.13V`   `Fe^(2+)(aq) + 2e^(-) rightarrow Fe(s)` `E^(@) = -0.44`   `Zn^(2+)(aq) + 2e^(-) rightarrow Zn(s)` `E^(@) = -0.76V`   Which species will reduce `Mn^(3+)` to `Mn^(2+) [E^(@) = 1.51V` but will NOT reduce `Cr^(3+) to Cr^(2+) [E^(@) = -0.40V]`
