Question

Match the reaction in List 1 with the colour at the final stage in List 2.

Answer 1

(A) During the titration ${Mn{O}_4}^{-}/H^{+}/F{e}^{2+}$, the solution at the final stage is colorless.
(B) During the titration ${Mn{O}_4}^{-}/conc.O{H}^{-}/M{n}^{2+}$, the solution at the final stage is green.
(C) During the titration ${Mn{O}_4}^{-}/H_{2}O/dil.O{H}^{-}$, the solution at the final stage is blackish brown.
(D) During the titration $CuS{O}_4/KI$, the solution at the final stage is deep reddish brown.
