Which of the following represents redox reactions?

A

`Cr_(2)O_(7)^(2-)+2overset(ө)OHrarr2CrO_(4)^(2-)+H_(2)O`

B

`SO_(3)^(2-)+H_(2)O+I_(2)rarrSO_(4)^(2-)+2I^(ө)+2H^(o+)`

C

`Ca(OH)_(2)+Cl_(2)rarrCa(Ocl)_(2)+CaCl_(2)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
`(b), (c ), and (d)` are redox reactions.
In `(a)`, there in no change in the oxidation state `(+6)` of `Cr`.
