The above equation describes the chemical reaction between Iron (Fe) and Mercury(II) chloride (HgCl2), resulting in Iron(III) chloride (FeCl3) and Mercury (Hg). This reaction belongs to the category of redox reactions.
- Reaction conditions:
The reaction occurs when iron comes into contact with a solution of mercury(II) chloride. Specific conditions regarding temperature, pressure depend on the actual conditions of the laboratory.
- Reaction process:
When in contact with HgCl2, Fe is oxidized from Fe to Fe3+, while HgCl2 is reduced to Hg.
- Phenomena that occur:
When the reaction occurs, the phenomenon observed is that iron begins to dissolve gradually in the solution of mercury(II) chloride and metallic mercury appears. The solution will change from colorless to orange due to iron(III) chloride.
