Final answer:
The balanced chemical equation for the reaction between aqueous sodium hydroxide and aqueous iron(III) chloride is 2 NaOH(aq) + FeCl2(aq) → 2 NaCl(aq) + Fe(OH)2(s).
Step-by-step explanation:
The balanced chemical equation for the reaction between aqueous sodium hydroxide (NaOH(aq)) and aqueous iron(III) chloride (FeCl3(aq)) is:
2 NaOH(aq) + FeCl2(aq) → 2 NaCl(aq) + Fe(OH)2(s)
In this double-replacement reaction, sodium hydroxide and iron(III) chloride react to form sodium chloride and iron(II) hydroxide. Fe(OH)2(s) is the precipitate that forms during the reaction, indicating it is insoluble and separates from the solution.
