उत्तर
Adding ammonium hydroxide drop by drop to iron(III) chloride solution forms a reddish-brown precipitate of iron(III) hydroxide.
\[\ce{\underset{(Yellow solution)}{FeCl3} + 3NH4OH -> \underset{Ferric hydroxide}{\underset{(Reddish brown ppt.)}{Fe[OH]3\downarrow}}+ \underset{(Colourless solution)}{3NH4Cl}}\]
