Sodium thiosulphate is used in photography

Question

Sodium thiosulphate is used in photography (A) as AgBr grain is reduced to non-metallic silver (B) to convert metallic silver into silver salt (C) to remove reduced silver (D) to remove undecomposed AgBr in the form of Na3 [Ag(S2O3 )2] (a complex salt)

Q. Sodium thiosulphate is used in photography

as $A g B r$ grain is reduced to non-metallic silver

to convert metallic silver into silver salt

to remove reduced silver

to remove undecomposed $A g B r$ in the form of $N a_{3} [A g (S_{2} O_{3})_{2}]$ (a complex salt)

In photography, used $A g B r$ is removed with the help of sodium thiosulphate, i.e., hypo.

$silver bromide A g B r + sodium thiosulphate 2 N a_{2} S_{2} O_{3} ⟶ sodium argento thiosulphate N a_{3} [A g (S_{2} O_{3})_{2}] + N a B r$
