kiruha [24]

Answer:

The equation is based on Iron (III) not lorn(III)

Explanation:

FeCl₃(aq) + 3 NaOH(aq) ---> Fe(OH)_{3(s)} + 3 NaCl(aq)

[ Balanced Molecular Equation ]

Fe^{3+(aq)} + 3Cl^{-(aq)} + 3Na^{+(aq)} + 3OH^{-(aq)} ---> Fe(OH)_{3(s)} + 3 Na^{+(aq)} + 3Cl^{-(aq)}

[ Balanced Full Ionic Equation ]

Fe^{3+(aq)} + 3 OH^{-(aq)} ---> Fe(OH)_{3(s)} Fe(OH)3(s)
