Advertisements
उत्तर
Iron (III) chloride on reacting with sodium hydroxide forms brown ppt.
\[\ce{FeCl3(aq) + 3NaOH(aq) -> \underset{\text{brown}}{ Fe(OH)3(s)} + 3NaCl(aq)}\]
Iron (II) chloride on reacting with sodium hydroxide forms green ppt.
\[\ce{FeCl2(aq) + 2NaOH(aq) -> \underset{\text{green}}{Fe(OH)2(s)} + 2NaCl(aq)}\]
