Final answer:
The balanced net ionic equation for the reaction between Fe(NO3)2(aq) and KOH(aq) is Fe2+(aq) + 2 OH-(aq) → Fe(OH)2(s), forming a precipitate of iron(II) hydroxide.
Step-by-step explanation:
The balanced net ionic equation for the reaction that occurs when Fe(NO3)2(aq) reacts with KOH(aq) is represented as follows:
Fe2+(aq) + 2 OH-(aq) → Fe(OH)2(s)
In this reaction, iron(II) ions (Fe2+) from iron(II) nitrate react with hydroxide ions (OH-) from potassium hydroxide to form a precipitate of iron(II) hydroxide (Fe(OH)2). Potassium ions (K+) and nitrate ions (NO3-) remain in solution and are not part of the net ionic equation, as they are spectator ions.
