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
Redox reactions are those reactions which involve change
in oxidation number of the reactants.

Answer 1

Answer:

option d is correct because it is a double displacement reaction in which meatual exchange of radicals takesplace and there is no change in oxidation states before and after the reaction of an element
