Vedclass · Answer

(C) metal can displace another metal from its salt solution if it has a more negative standard reduction potential (i.e.,it is a stronger reducing agent).Given values are $E^o_A = -0.250 \ V$,$E^o_B = -0.140 \ V$,$E^o_C = -0.126 \ V$,and $E^o_D = -0.402 \ V$.Comparing these,only $D$ has a more negative reduction potential than $A$ $(E^o_D Therefore,$D$ can displace $A$ from its aqueous salt solution.

The standard reduction electrode potentials of four metals are $A = -0.250 \ V$,$B = -0.140 \ V$,$C = -0.126 \ V$,and $D = -0.402 \ V$. Which metal can displace $A$ from its aqueous salt solution?
