The chemical equation FeCl2 + KOH -> Fe(OH)2 + 2KCl.

  1. The chemical equation above describes the exchange reaction between iron(II) chloride (FeCl2) and potassium hydroxide (KOH) to produce iron(II) hydroxide (Fe(OH)2) and potassium chloride (KCl).

  2. Reaction conditions: The reaction is carried out in an aqueous solution environment.

  3. Reaction process: Iron(II) chloride in the solution will react with potassium hydroxide also in solution to form precipitated iron(II) hydroxide and released potassium chloride.

  4. Phenomenon observed: During the reaction process, we can observe that iron(II) hydroxide is a greenish precipitate appearing in the solution.
