- Detailed information about the equation 2Na + 2H2O -> 2NaOH + H2:
This equation represents the reaction process between sodium (Na) and water (H2O) to form sodium hydroxide (NaOH), also known as caustic soda, and hydrogen (H2).
- Reaction conditions:
This reaction easily occurs at ambient temperature and normal atmospheric pressure. Sodium needs to be cut into small pieces before being introduced into water to increase the contact area and reaction speed.
- Reaction process:
When sodium comes into contact with water, the reaction occurs immediately. Sodium separates hydrogen from water and forms caustic soda. During this process, hydrogen escapes in the form of gas.
- Phenomena occurring:
When the reaction takes place, sodium melts in water and creates a white liquid, which is caustic soda. At the same time, the escaping hydrogen gas creates bubbles on the liquid surface. This reaction also generates heat, so it can be observed that the water starts to boil and the sound of escaping hydrogen gas can be heard.
