The chemical equation above represents the reaction process between Chromium (Cr) metal and Chlorine gas (Cl2), resulting in the compound Chromium trichloride (CrCl3). This equation is balanced, meaning that the number of moles of each element on both sides of the reaction is equal.
- Reaction conditions:
The reaction occurs when Chromium metal is placed in an environment containing Chlorine gas, usually at high temperatures.
- Reaction process:
When Chromium and Chlorine gas come into contact with each other in a high-temperature environment, Chlorine molecules will disintegrate into Chlorine atoms and then react with Chromium to form the compound Chromium trichloride.
- Occurring phenomenon:
When the reaction occurs, the Chromium metal will gradually “disappear” and the reaction product, Chromium trichloride, will appear. This product has a color ranging from blue to green.
