Which of the following does not represent redox reaction?

A

`Cr_(2)O_(7)^(2-)+2overset(ɵ)(O)HtoCrO_(4)^(2-)+H_(2)O`

B

`SO_(5)^(2-)+2I^(ɵ)+2H^(o+)toI_(2)+SO_(4)^(2-)`

C

`2Ca(OH)_(2)+2Cl_(2)toCa(ClO)_(2)+CaCl_(2)+2H_(2)O`

D

`PCl_(5)toPCl_(3)+Cl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
In basic medium `Cr_(2)O_(7)^(2-)` changes to `CrO_(4)^(2-)` (no change in oxidation number).
