Answer

Iron(III) Nitrate and Potassium Hydroxide Reaction

Reaction of Potassium Hydroxide with Iron(III) Nitrate

🧪 Formula Equation

Fe(NO3)3 (aq) + 3KOH (aq) → Fe(OH)3 (s) + 3KNO3 (aq)
Iron(III) hydroxide precipitates as a brown solid, while potassium nitrate remains dissolved in solution.

💧 Complete Ionic Equation

Fe3+ (aq) + 3NO3– (aq) + 3K+ (aq) + 3OH– (aq) → Fe(OH)3 (s) + 3K+ (aq) + 3NO3– (aq)
All soluble compounds are shown dissociated into ions. The solid Fe(OH)3 does not dissociate.

🧾 Net Ionic Equation

Fe3+ (aq) + 3OH– (aq) → Fe(OH)3 (s)
The net ionic equation focuses only on the chemical species that undergo change, omitting the spectator ions.
