A) the solution becomes blue
B) \[S{{O}_{2}}\]gets reduced
C) \[C{{r}_{2}}{{(S{{O}_{4}})}_{3}}\]is formed
D) the solution becomes colorless
Correct Answer: C
Solution :
\[CrO_{7}^{2-}+3S{{O}_{2}}+2{{H}^{+}}\xrightarrow{{}}\underset{\begin{smallmatrix} chromium \\ \,\,\,sulphate \end{smallmatrix}}{\mathop{C{{r}_{2}}{{(S{{O}_{4}})}_{3}}}}\,+{{H}_{2}}O\]You need to login to perform this action.
