Question 18

In which conversion is the transition metal oxidised?

A

MnO4−→Mn2+\text{MnO}_4^{-} \rightarrow \text{Mn}^{2+}MnO4−​→Mn2+

B

VO2+→VO2+\text{VO}_2^{+} \rightarrow \text{VO}^{2+}VO2+​→VO2+

C

Cr3+→CrO42−\text{Cr}^{3+} \rightarrow \text{CrO}_4^{2-}Cr3+→CrO42−​

D

MnO42−→MnO2\text{MnO}_4^{2-} \rightarrow \text{MnO}_2MnO42−​→MnO2​
