A) The solution turns blue
B) The solution is decolourized
C) \[\text{S}{{\text{O}}_{\text{2}}}\]is reduced
D) Green \[C{{r}_{2}}{{(S{{O}_{4}})}_{3}}\]is formed
Correct Answer: D
Solution :
[d] \[{{K}_{2}}C{{r}_{2}}O{{}_{7}}+S{{O}_{2}}+{{H}_{2}}S{{O}_{4}}\]\[\to {{K}_{2}}S{{O}_{4}}+\underset{\text{green colour}}{\mathop{C{{r}_{2}}{{(S{{O}_{4}})}_{3}}+{{H}_{2}}O}}\,\]You need to login to perform this action.
