Question

Which of the following is not an example of redox reaction? (A)  CuO + H2 → Cu + H2O (B)  Fe2O3 + 3CO → 2Fe + 3CO2  (C)  2K + F2 → 2KF (D)  BaCl2 + H2SO4 → BaSO4 + 2HCl

BaCl2 + H2SO4 → BaSO4 + 2HCl is not a redox reaction as it does not involve any change in oxidation number. It is an example of double decomposition reaction.

Q. Which of the following is not an example of redox reaction?

$C u O + H_{2} \to C u + H_{2} O$

$F e_{2} O_{3} + 3 CO \to 2 F e + 3 C O_{2}$

$2 K + F_{2} \to 2 K F$

$B a C l_{2} + H_{2} S O_{4} \to B a S O_{4} + 2 H Cl$

$B a C l_{2} + H_{2} S O_{4} \to B a S O_{4} + 2 H Cl$ is not a redox reaction as it does not involve any change in oxidation number. It is an example of double decomposition reaction.
