The equation is Fe + 2KOH -> Fe(OH)2 + 2K

  1. Detailed information about the equation Fe + 2KOH -> Fe(OH)2 + 2K:

    • Fe is the chemical symbol for iron, a chemical element belonging to group 8, period 4 of the periodic table.
    • KOH is the chemical symbol for potassium hydroxide, a chemical compound composed of potassium, oxygen, and hydrogen.
    • Fe(OH)2 is the chemical symbol for iron(II) hydroxide, a chemical compound composed of iron, oxygen, and hydrogen.
    • K is the chemical symbol for potassium, a chemical element belonging to group 1, period 4 of the periodic table.

  2. Reaction conditions:

    • The reaction requires temperature, pressure, and basic conditions.

  3. Reaction process:

    • Iron reacts with potassium hydroxide to form iron(II) hydroxide and potassium.

  4. Phenomena occurring:

    • During the reaction, the solid iron will gradually dissolve, replaced by the formation of the green solid of iron(II) hydroxide. The produced potassium will emit heat and burn with a characteristic purple color.
