A) \[S{{O}_{2}},Cr{{O}_{4}}^{-2}\]
B) \[S{{O}_{2}},Cr{{O}_{7}}^{-2}\]
C) \[S{{O}_{3}},Cr{{O}_{4}}^{-2}\]
D) \[S{{O}_{3}}^{-2},Cr{{O}_{4}}^{-2}\]
Correct Answer: C
Solution :
Oxidation number of S in \[S{{O}_{3}}\] \[x+(3\times -2)=0\] \[x=6\] The oxidation number of \[Cr\] in \[Cr{{O}_{4}}^{2-}\] \[x+(4\times -2)=-2\] \[x=8-2=6\]
