Vedclass · Answer

(D) The solubility of silver bromide $(AgBr)$ in sodium thiosulfate $(Na_2S_2O_3)$,commonly known as 'hypo' solution,occurs due to the formation of a soluble complex ion.The chemical reaction is:$AgBr_{(s)} + 2 Na_2S_2O_{3(aq)} \rightarrow Na_3[Ag(S_2O_3)_2]_{(aq)} + NaBr_{(aq)}$In this reaction,the complex ion formed is $[Ag(S_2O_3)_2]^{3-}$.Therefore,option $D$ is correct.

The solubility of silver bromide in hypo solution is due to the formation of :
