Question 15

In which conversion is the transition metal oxidized?

A

MnO42−→MnO4−\text{MnO}_4^{2-} \rightarrow \text{MnO}_4^{-}MnO42−​→MnO4−​

B

VO2+→V3+\text{VO}_2^{+} \rightarrow \text{V}^{3+}VO2+​→V3+

C

CrO42−→Cr2O72−\text{CrO}_4^{2-} \rightarrow \text{Cr}_2\text{O}_7^{2-}CrO42−​→Cr2​O72−​

D

[Co(H2O)6]3+→[Co(H2O)6]2+[\text{Co(H}_2\text{O)}_6]^{3+} \rightarrow [\text{Co(H}_2\text{O)}_6]^{2+}[Co(H2​O)6​]3+→[Co(H2​O)6​]2+
