Chemistry Question on Classical Idea Of Redox Reactions – Oxidation And Reduction Reactions
Which reaction is NOT a redox reaction?
A
Zn+CuSO4-> ZnSO4 + Cu
B
2KCIO3+l2 -> 2KIO3 + Cl2
C
H2+Cl2 -> 2HCI
D
BaCl2 + Na2SO4 -> BaSO4 + 2NaCl
Answer
BaCl2 + Na2SO4 -> BaSO4 + 2NaCl
Explanation
Solution
- A redox reaction involves the transfer of electrons, leading to oxidation and reduction.
- In option (3), there is no change in oxidation states of elements; it is a simple double displacement reaction.
- In other options, electron transfer occurs, qualifying them as redox reactions.
