,A. The iron ion is acting like a base. It is forcing water
to give up a hydronium ion, which agrees with the
Brønsted-Lowry definition of an acid.
B. The iron ion is acting like an acid. It has accepted a
pair of electrons from the oxygen, which agrees with
the Lewis definition of an acid.
C. The iron is not acting like either an acid or a base. It
is a reducing agent because it has been oxidized.
D. The iron ion is acting like an acid. It is removing
hydroxide from the solution, which agrees with the
Arrhenius definition of an acid. - Answer>> B. The iron
ion is acting like an acid. It has accepted a pair of
electrons from the oxygen, which agrees with the Lewis
definition of an acid.
