Solution

The correct option is D (A)-4, (B)-3, (C)- 1, (D)-2
A) $2 N a_{2} S_{2} O_{3} + I_{2} \to N a_{2} S_{4} O_{6} + 2 N a I$ In this reaction, sodium thiosulphate acts as a reducing agent and reduces Iodine.
$(B) N a_{2} S_{2} O_{3} + d i l . H a \to N a C l + S O_{2} + S + H_{2} O$
$(C) N a_{2} S_{2} O_{3} + A g N O_{3} \to A g_{2} S_{2} O_{3}$
complex compound used in photographic films.
$(D) N a_{2} S_{2} O_{3} + A g B r \to A g_{2} S + N a B r$
