Vedclass · Answer

(A) The reaction of thiosulfate ions with silver ions proceeds as follows:$1$. $Ag^{+} + 2S_2O_3^{2-} \rightarrow \left[Ag(S_2O_3)_2\right]^{3-}$ (This is the clear solution $X$)$2$. $\left[Ag(S_2O_3)_2\right]^{3-} + Ag^{+} \rightarrow Ag_2S_2O_3(\downarrow)$ (This is the white precipitate $Y$)$3$. $Ag_2S_2O_3 + H_2O \rightarrow Ag_2S(\downarrow) + H_2SO_4$ (The white precipitate turns into a black precipitate $Z$ of silver sulfide over time due to hydrolysis).

In the following reaction sequence in aqueous solution,the species $X, Y$ and $Z$,respectively,are
