Vedclass · Answer

(C) The reaction of $AgNO_3$ with various anions produces different precipitates: $1$. $Br^-$ forms $AgBr$ (pale yellow ppt.),which is soluble in excess $NH_3$. $2$. $I^-$ forms $AgI$ (yellow ppt.),which is insoluble in $NH_3$. $3$. $PO_4^{3-}$ forms $Ag_3PO_4$ (yellow ppt.),which is soluble in $NH_3$. $4$. $AsO_3^{3-}$ forms $Ag_3AsO_3$ (yellow ppt.),which is soluble in $NH_3$. Since $AgI$ is the only yellow precipitate among these that is insoluble in excess $NH_3$,the salt $X$ cannot contain $I^-$.

$X$ (salt) + $AgNO_3$ $(aq.) \to \underset{(\text{Yellow ppt.})}{Y \downarrow}$ (soluble in excess of $NH_3$ solution). Salt $X$ does not contain:
