- Detailed information about the equation Na2CO3 + CO2 -> 2NaHCO3
- This is a chemical equation representing the reaction of sodium carbonate (Na2CO3) with carbon dioxide (CO2) to form sodium bicarbonate (NaHCO3), also known as sodium hydrogen carbonate.
- Na2CO3 (abbreviated as soda or edible soda) is a white, odorless solid that can dissolve in water to form a mild alkaline solution.
- CO2 (carbon dioxide) is a colorless, odorless gas found in the air and is known for its role as a greenhouse gas.
- NaHCO3 (sodium bicarbonate or baking soda) is a white solid that can dissolve in water, commonly used in cooking and baking.
- Reaction conditions
- This reaction requires the presence of water vapor (H2O) to occur.
- The temperature needs to be controlled at an appropriate level, usually at room temperature.
- Reaction process
- Firstly, sodium carbonate reacts with water vapor and carbon dioxide to form sodium bicarbonate.
- This process takes place according to the following formula: Na2CO3 + H2O + CO2 -> 2NaHCO3
- Occurrences
- During the reaction process, the solid sodium carbonate will gradually disappear and the solution will turn to the white color of sodium bicarbonate.
- If the reaction is carried out in a sealed container, you will see the pressure inside the container increase due to the release of carbon dioxide gas.
