What is the part of the reaction that involves only oxidation or reduction?

It's not entirely clear what the question is asking... but
oxidation involves the loss of electrons from an atom or ion, and
reduction involves the gain of electrons. The other parts of a
redox (reduction-oxidation) reaction may involve atoms forming and
breaking bonds, but the oxidation or reduction part is just about
losing or gaining electrons. You might be talking about what is
called a "half-reaction." A half-reaction is the part of the
reaction that is only either the oxidation step or the reduction
step. Neither is a complete reaction, but put together the two
half-reactions give the overall reactions. In the oxidation
half-reaction, electrons come out as products, and in the reduction
half-reaction electrons go in as reactants. Remember: OIL RIG
Oxidation Is Loss; Reduction Is Gain.
