$p$-Amino- $N, N$-dimethylaniline is added to a strongly acidic solution of ${X}$. The resulting solution is treated with a few drops of aqueous solution of ${Y}$ to yield blue coloration due to the formation of methylene blue. Treatment of the aqueous solution of ${Y}$ with the reagent potassium hexacyanoferrate$(II)$ leads to the formation of an intense blue precipitate. The precipitate dissolves on excess addition of the reagent. Similarly, treatment of the solution of ${Y}$ with the solution of potassium hexacyanoferrate$(III)$ leads to a brown coloration due to the formation of ${Z}$.
