A) \[{{O}_{2}}\]
B) \[C{{l}_{2}}\]
C) \[CrOC{{l}_{2}}\]
D) \[Cr{{O}_{2}}C{{l}_{2}}\]
Correct Answer: D
Solution :
This reaction is used to confirm the presence of \[C{{l}^{-}}\] ion in a mixture. In this, orange-red vapours of chrornyl chloride obtained on heating the reaction mixture. \[4NaCl+{{K}_{2}}C{{r}_{2}}{{O}_{7}}+6{{H}_{2}}S{{O}_{4}}\xrightarrow{\Delta }2KHS{{O}_{4}}\] \[+\,4NaHS{{O}_{4}}+\underset{\text{Orange-red}}{\mathop{2Cr{{O}_{2}}C{{l}_{2}}\uparrow }}\,+3{{H}_{2}}O\]You need to login to perform this action.
