FeCl3(aq) + 3 NaOH (aq) ---- Fe(OH)3(s) + 3 NaCl(aq)

Is this a redox reaction in the reaction above? Explain.

Solutions

Expert Solution

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

It is not a redox reaction. Because each element in the above reaction has same oxidation number at both reactants side and products side.

Fe in FeCl3 = + 3

Fe in Fe(OH)3 = + 3

Na in NaOH = + 1

Na in NaCl = + 1

Cl in FeCl3 = - 1

Cl in NaCl = - 1

OH in NaOH = - 1

OH in Fe(OH)3 = - 1

Since, there is no change in oxidation number of any element, the reaction is not a redox reaction.
