The above chemical equation describes the decomposition process of table salt (sodium chloride – NaCl) to produce sodium elements (Na) and chlorine gas (Cl2).
- Reaction conditions
This reaction requires a very high temperature (approximately 801 °C) to take place.
- Reaction process
When heated to the required temperature, table salt (NaCl) decomposes into sodium and chlorine gas. Sodium will be in vapor form due to the high temperature, while chlorine gas will escape from the reaction process.
- Phenomena occurring
The phenomena that occur during the reaction include the appearance of heat and the transformation of table salt into sodium in vapor form and chlorine gas. Therefore, this reaction needs to be carried out in a tightly controlled environment to avoid the risk of fire and explosion.
