A) \[{{H}_{2}}S{{O}_{4}}\]
B) \[N{{a}_{2}}S\]
C) \[N{{a}_{2}}S{{O}_{4}}\]
D) \[N{{a}_{2}}{{S}_{2}}{{O}_{3}}\]
Correct Answer: D
Solution :
Hypo \[(N{{a}_{2}}{{S}_{2}}{{O}_{3}})\] decolorizes iodine solution. \[2N{{a}_{2}}{{S}_{2}}{{O}_{3}}+{{I}_{2}}\xrightarrow{{}}2NaI+\underset{\begin{smallmatrix} Sodium\,tetra \\ thionate \end{smallmatrix}}{\mathop{N{{a}_{2}}{{S}_{4}}{{O}_{6}}}}\,\]
