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).
- Reaction Conditions
This reaction occurs under normal temperature and pressure conditions.
- 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).
- 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.
