Colour of iodine solution is disappeared by shaking it with aqueous solution of
- A${H_2}S{O_4}$
- B$N{a_2}S$
- ✓$N{a_2}{S_2}{O_3}$
- D$N{a_2}S{O_4}$
✓
Answer
Correct option: C.
$N{a_2}{S_2}{O_3}$
c
(c) $2N{a_2}{S_2}{O_3} + {I_2}\, \to \,2NaI + N{a_2}{S_4}{O_6}$
(c) $2N{a_2}{S_2}{O_3} + {I_2}\, \to \,2NaI + N{a_2}{S_4}{O_6}$
