प्रश्न
Write balanced equation reaction of sodium hydroxide solution with iron (III) chloride solution.
उत्तर
Adding sodium hydroxide solution dropwise to FeCl3 produces a reddish coloured ppt that is insoluble in excess NaOH.
\[\ce{\underset{\underset{(yellow)}{Ferric chloride}}{FeCl3} + \underset{\underset{(colourless)}{Caustic soda}}{3NaOH} → \underset{\underset{(reddish brown ppt.)}{Ferric hydroxide}}{Fe(OH)3↓} + \underset{\underset{(colourless)}{Sodium chloride}}{3NaCl}}\]
