The above equation represents the decomposition reaction of the compound mercury bromide (Hg2Br2) into mercury (Hg) and bromine (Br2).
- Reaction conditions
This reaction requires high temperature or exposure to light to stimulate. This is because mercury bromide has high chemical stability and is difficult to decompose under normal conditions.
- Reaction process
When heated or exposed to light, the Hg2Br2 molecules will receive energy and decompose into mercury and bromine.
- Phenomena that occur
In reality, this reaction is quite difficult to observe directly, because both mercury bromide and mercury do not have characteristic colors. However, you can see the transformation from the solid state of mercury bromide to the solid state of mercury and the characteristic brown color of bromine gas.
