Answer :
Sodium bicarbonate and citric acid are used in this activity's interaction to create water and carbon dioxide.
HCO3- (aq) + H+ (aq) H2O (l) + CO2 (g)
- Citric acid and sodium bicarbonate (NaHCO3) are also present in the pills
- Hydrogen ions (H+) and bicarbonate (HCO3-) are created when the tablet dissolves in water.
- The two compounds can then react in accordance with the reaction described above once they are in solution.
- The HCO3- and H+ must contact at the proper angle and with the appropriate amount of energy for the reaction to take place.
- Since there are more opportunities for collisions when the tablet is broken into more pieces and when the temperature is higher because the molecules are moving more quickly, the likelihood of this happening increases.
- Students will test out several scenarios for how Alka Seltzer tablets and water interact in this project.
- Students will start to understand what variables chemical engineers can regulate to achieve the desired outcome by varying temperature and the surface area available for reaction.
- It is customary to complete this task before making rockets in order to familiarize oneself with the reaction's characteristics before employing it in the Alka Seltzer Rockets exercise.
Hence, Sodium bicarbonate and citric acid are used in this activity's interaction to create water and carbon dioxide.
