Question : Which of the following statements about the given reaction are correct?
MnO2 + HCl ------------> MnCl2 + Cl2 + H2O
(i) MnO2 is getting oxidised.
(ii) MnO2 is getting reduced.
(iii) MnO2 is acting as reducing agent.
(iv) MnO2 is acting as oxidizing agent.
Which is the correct combination?
a) (i), and (iii)
(b) (i) and (iv)
(c) (ii), and (iv)
(d) (ii) and (iii)
Correct Answer : option C: (ii) and (iv)
Explanation :
MnO2 + HCl ------------> MnCl2 + Cl2 + H2O
in the above chemical equation, MnO2 is getting reduced to MnCl2 as reduction is called as removal of oxygen.
MnO2 is acting as Oxidizing agent for HCl to become H2O as oxidation is called as addition of oxygen.
Hence the option c is correct.
