The equation Fe + 2HgCl2 -> FeCl2 + 2Hg

  1. Detailed Information about the Reaction Fe + 2HgCl2 -> FeCl2 + 2Hg

The above equation represents the reaction between iron (Fe) and mercury(II) chloride (HgCl2), resulting in the formation of iron(II) chloride (FeCl2) and mercury (Hg).

  1. Reaction Conditions

This reaction occurs under normal temperature and pressure conditions.

  1. Reaction Process

Fe + 2HgCl2 -> FeCl2 + 2Hg is a redox reaction. Iron (Fe) is oxidized from an oxidation state of 0 to +2, forming FeCl2, while mercury(II) in HgCl2 is reduced from an oxidation state of +2 to 0, forming pure mercury (Hg).

  1. Phenomena Occurring

When iron (Fe) reacts with mercury(II) chloride (HgCl2), a gas is released, the mercury(II) chloride disappears and a black layer appears on the outside of the iron due to the adherence of mercury. In addition, when iron reacts with mercury(II) chloride, iron(II) chloride salt is also produced.
