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.
-
Reaction conditions:
- The reaction requires temperature, pressure, and basic conditions.
-
Reaction process:
- Iron reacts with potassium hydroxide to form iron(II) hydroxide and potassium.
-
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.
