Which of the statements about the reaction below are incorrect?

$$ 2PbO(s) + C(s)$$

$$ \downarrow $$

$$ 2Pb(s) + CO_2 $$

  • (a) Lead is getting reduced.
  • (b) Carbon dioxide is getting oxidised.
  • (c) Carbon is getting oxidised.
  • (d) Lead oxide is getting reduced
  • (i) (a) and (b)
  • (ii) (a) and (c)
  • (iii) (a), (b) and (c)
  • (iv) all


Answer :

(i) a and b

Reason -
Oxidation is a reaction in which oxygen combines with another substance.
Reduction is a reaction in which a compound is deprived of all, or part, of the oxygen it contains.
Thus in mentioned reaction:
Carbon is getting oxidised(since oxygen has been added to it)
Lead Oxide is getting reduced (since oxygen has been removed from it)
