Answer:
(a) In this reaction, HCI has been oxidized to CI2
(Removal of H) andhas
been reduced to (Removal
of O). Hence,is
the oxidizing agent (oxidant)
(b) Mg has been oxidized to(Addition
of O). Hence, O2 is the oxidant.
(c) This reaction occurs as
Herehas
gained two electrons to form Cu. Hence,has
been reduced to Cu.
But Zn has donated two electrons to form.
Hence, Zn has been oxidized to.
Thus, is
the oxidizing agent.
(d) Ca has been oxidized to(Addition
of oxygen), whereashas
been reduced to V. Hence,is
the oxidant.
(e) Fe has been oxidized towhereas
H2O has been reduced to Hg. Hence, H2O is the oxidant.
(f)has
been reduced to Cu whereas H2 has been oxidized to H2O.
Hence,is
the oxidant.
