The equation Fe + 2NaOH -> Fe(OH)2 + 2Na

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

    • Fe is the symbol for Iron, a chemical element with an atomic number of 26.
    • NaOH is the symbol for Sodium hydroxide, a chemical compound with the formula NaOH.
    • Fe(OH)2 is the symbol for Iron (II) hydroxide, a chemical compound with the formula Fe(OH)2.
    • Na is the symbol for Sodium, a chemical element with an atomic number of 11.

  2. Reaction conditions: The reaction takes place at room temperature.

  3. Reaction process: When iron reacts with sodium hydroxide, it produces iron (II) hydroxide and sodium.

  4. Occurring phenomena: When the reaction occurs, iron is oxidized from the non-oxidized state (Fe0) to the +2 state (Fe(OH)2), creating a greenish layer on the surface of the iron, which is iron (II) hydroxide. At the same time, sodium hydroxide is reduced to sodium. We observe the gray iron beginning to be covered by a greenish layer and sodium being released.
