The equation Fe(NO3)3 + 3KOH -> Fe(OH)3 + 3KNO3

  1. The chemical equation above describes the neutralization reaction between nitric acid Fe(NO3)3 and potassium hydroxide KOH, resulting in the precipitation of iron (III) hydroxide Fe(OH)3 and the salt KNO3.

  2. Reaction conditions:

    • The reaction occurs at room temperature.
    • There must be sufficient amount of reactants.

  3. Reaction process:

    • It starts by reacting Fe(NO3)3 with KOH.
    • When the reaction happens, it forms a brown precipitate of iron (III) hydroxide and potassium nitrate salt, while releasing heat.

  4. Phenomena observed:

    • When Fe(NO3)3 reacts with KOH, a brown precipitate appears. That is Fe(OH)3.
    • If you continue to stir, this precipitate will settle at the bottom of the dish.
    • Meanwhile, the remaining solution will contain the salt KNO3.
