Vedclass · Answer

(C) The ability of a metal to reduce $H_2O$ depends on its position in the electrochemical series. Metals that are more reactive than hydrogen (those with negative standard reduction potentials) can displace hydrogen from $H_2O$. $Ca$,$Fe$,and $Li$ have negative standard reduction potentials and can reduce $H_2O$. $Cu$ has a positive standard reduction potential $(E^o = +0.34 \ V)$,meaning it is less reactive than hydrogen and cannot reduce $H_2O$ to $H_2$ gas.

Which of the following metals will not reduce $H_2O$?
