A) \[{{K}_{2}}C{{O}_{3}}\]
B) \[{{K}_{3}}P{{O}_{4}}\]
C) \[KBr\]
D) \[KI\]
Correct Answer: D
Solution :
\[2CuS{{O}_{4}}+4KI\xrightarrow{{}}2{{K}_{2}}S{{O}_{4}}+\underset{white\,\,ppt.}{\mathop{2CuI}}\,+\underset{\begin{smallmatrix} Brown\,\,colour \\ in\,\,solution \end{smallmatrix}}{\mathop{{{I}_{2}}}}\,\]\[\underset{Hypo}{\mathop{2N{{a}_{2}}{{S}_{2}}{{O}_{3}}}}\,+{{I}_{2}}\xrightarrow{{}}\underset{sodium\,\,tetrathionate\,colourless}{\mathop{N{{a}_{2}}{{S}_{4}}{{O}_{6}}+2NaI}}\,\]You need to login to perform this action.
