A) \[C{{r}_{2}}{{O}_{3}}\]
B) \[CrO_{4}^{2-}\]
C) \[C{{r}_{2}}{{(S{{O}_{4}})}_{3}}\]
D) \[Cr{{O}_{5}}\]
Correct Answer: D
Solution :
\[{{K}_{2}}C{{r}_{2}}{{O}_{7}}+{{H}_{2}}S{{O}_{4}}+4{{H}_{2}}{{O}_{2}}\to \] \[{{K}_{2}}S{{O}_{4}}+5{{H}_{2}}O+\underset{\text{dark}\,\text{blue}}{\mathop{2Cr{{O}_{5}}}}\,\]You need to login to perform this action.
