Which of the following is not a redox reaction

A

`KCl+K_(2)Cr_(2)O_(7)+con.H_(2)SO_(4)rarrCrO_(2)Cl_(2)+K_(2)SO_(4)+H_(2)O`

B

`K_(2)Cr_(2)O^(7)+H_(2)O_(2)con.H_(2)SO_(4)rarrK_(2)SO_(4)+CrO_(5)+H_(2)O`

C

`K_(2)Cr_(2)O^(7)+H_(2)O_(2)+dil.H_(2)SO_(4)rarrK_(2)SO_(4)+Cr_(2)(SO_(4))_(3)+7H_(2)O+3O_(2)`

D

`K_(2)Cr(_(2)O^(7)+2KOHrarr2K_(2)CrO_(4)+H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
D
`K_(2)Cr_(2)O_^(7)+KOHrarrK_(2)CrO_(4)+H_(2)O`
Oxidation state of Cr will remain same in reactant as well as product.
