Question

Match the reagents (in List I) with the anions (in List II) which can be identified.

Answer 1

The reagent ${AgNO}_3$ is used in the identification of the anions ${Cl}^{-}$, ${Br}^{-}$, $I^{-}$ and ${CrO}_4^{2-}$.
The reagent ${FeCl}_3$ is used in the identification of the anion ${CH}_3{COO}^{-}$.
The reagent ${BaCl}_2$ is used in the identification of the anion ${CrO}_4^{2-}$.
The reagent $({CH}_{3}COO{)}_{2}Pb$ is used in the identification of the anions $I^{-}$ and ${CrO}_4^{2-}$.
The reagent ${Cl}_2$ water is used in the identification of the anions ${Br}^{-}$ and $I^{-}$.
