Vedclass · Answer

(C) In photography,sodium thiosulphate $(Na_2S_2O_3 \cdot 5H_2O)$,commonly known as 'hypo',is used as a fixing agent. It dissolves the unexposed silver bromide $(AgBr)$ from the photographic film by forming a soluble complex,sodium dithiosulphatoargentate$(I)$,according to the reaction: $AgBr(s) + 2Na_2S_2O_3(aq) \rightarrow Na_3[Ag(S_2O_3)_2](aq) + NaBr(aq)$. Therefore,its utility is due to its complex-forming behaviour.
