Which of the following is not a redox reaction?

A

`CaCO_(3)rarrCaO+CO_(2)`

B

`O_(2)+2H_(2)rarr2H_(2)O`

C

`Na+H_(2)OrarrNaOH+1//2H_(2)`

D

`MnCI_(3)rarr?MnCI_(2)+1//2CI_(2)`

Text Solution

Verified by Experts

`(overset(+2)Ca overset(-2)O_(3))^(+4)rarroverset(+2)Caoverset(-2)O+overset(+2)Coooverset(-2)O_(2)`
This is not a redo reaction because no element undergoeso changes in oxidation number
