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

A

`CuO+H_(2)rarrCu+H_(2)O`

B

`Fe_(2)O_(3)+3CO rarr 2Fe + 3 CO_(2)`

C

`2K+F_(2) rarr 2KF`

D

`BaCl_(2)+H_(2)SO_(4) rarr BaSO_(4)+2HCl`

Text Solution

Verified by Experts

The correct Answer is:
D
`BaCl_(2)+H_(2)SO_(4)rarr BaSO_(4)+2HCl` is not a redox reaction as it does not involve any change in oxidation number. It is an example of double decomposition reaction.

Redox is a reaction in which both oxidation and reduction will take place simultaneously . It is obvious that if one substance gives electron there must be another substance to accept these electrons . In some reactions, same substance is reduced as well as oxidised, these reactions are termed as disproportionation reactions. For calculating equivalent mass in redox reaction change in oxidtaion number is realted to n-factor which is reciprocal of molar ratio. Which of the following is an example of redox reaction ?
