उत्तर
Adding sodium hydroxide solution dropwise to FeCl3 produces a reddish coloured ppt that is insoluble in excess NaOH.
\[\ce{\underset{(yellow)}{\underset{Ferric chloride}{FeCl3}} + \underset{(colourless)}{\underset{Caustic soda}{3NaOH}} -> \underset{(reddish brown ppt{.})}{\underset{Ferric hydroxide}{Fe(OH)3↓}} + \underset{(colourless)}{\underset{Sodium chloride}{3 NaCl}}}\]
