Can the reaction, `Cr_(2)O_(7)^(2-) + H_(2)O rarr 2CrO_(4)^(2-) + 2H^(+)`be regarded as a redox reaction ?

Text Solution

Verified by Experts

In this reaction ,
Oxidation number of Cr in `Cr_2O_7^(2-) =+6`
Oxidation number of Cr in `CrO_4^(2-) = +6`
Since during this reaction , the oxidation number of Cr has neither increased nor decreased , therefore , the above reaction cannot be regarded as a redox reaction.
