Question

Iodine and hypo react to produce :
$N a_{2} S$
$N a_{2} S O_{3}$
$N a_{2} S_{4} O_{6}$
$N a_{2} S O_{4}$

A

N a_{2} S O_{4}

B

N a_{2} S

C

N a_{2} S O_{3}

D

Solution

Verified by Toppr

Iodine and hypo react to produce $N a_{2} S_{4} O_{6}$

$I_{2} + 2 N a_{2} S_{2} O_{3} ⟶ 2 I_{2} + N a_{2} S_{4} O_{6} + 2 N a I$

Hence option D is correct.
