Solution

The compound A is $N a_{2} S_{2} O_{3}$ .
The compound Bis $A g_{2} S_{2} O_{3}$ .
The compound Cis $N a_{3} [A g (S_{2} O_{3})_{2}]$ .
The compound D is $A g_{2} S$ .
The compound E is $H_{2} S O_{4}$
The compound F is $B a S O_{4}$
$N a_{2} S_{2} O_{3}$ .reacts with silver nitrate of form white ppt which dissolves in excess of $N a_{2} S_{2} O_{3}$ ..
$N a_{2} S_{2} O_{3} + 2 A g N O_{3} \to A g_{2} S_{2} O_{3} + 2 N a N O_{3}$ .
$3 N a_{2} S_{2} O_{3} + A g_{2} S_{2} O_{3} \to 2 N a_{3} [A g (S_{2} O_{3})_{2}]$
When, the white ppt is heated with water, black ppt is obtained.
$A g_{2} S_{2} O_{3} ↓ (w h i t e) H_{2} O - - \to A g_{2} S (b l a c k) + H_{2} S O_{4}$ .
Sulphuric acid reacts with barium chloride to give white ppt of barium sulphate.
$B a C l_{2} + H_{2} S O_{4} \to B a S O_{4} + 2 H C l$
