Vedclass · Answer

(C) The reaction between acidified potassium chromate and $H_2O_2$ produces chromium pentoxide $(CrO_5)$,which is a blue-colored compound.The chemical reaction is: $K_2CrO_4 + 2H_2O_2 + 2H^+ \rightarrow CrO_5 + 2K^+ + 2H_2O$.$CrO_5$ has a butterfly-like structure.In this structure,there is one double-bonded oxygen atom $(Cr=O)$ and four single-bonded oxygen atoms $(Cr-O)$ which are part of two peroxo groups $(-O-O-)$.Therefore,the number of oxygen atoms bonded to chromium through only single bonds is $4$.
