Select True or False: PbO2 is oxidized in this process. (Batteries in our cars generate electricity by the following chemical reaction.) Pb + PbO2 + 2H2SO4 → 2PbSO4 + 2H2O

Answer :  The given statement is false.

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.

Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced. Thus, it will undergo reduction reaction.

The given chemical reaction is,

In this reaction, the oxidation state of Pb is (0), oxidation state of Pb in is (+4) and oxidation state of Pb in is (+2).

The oxidation-reduction half reaction will be :

Oxidation :

Reduction :

In this reaction, shows reduction that means it is reduced and Pb shows oxidation that means it is oxidized.

Hence, the given statement is false.
