A tablespoon of baking powder is added to 300g of water in a sturdy bottle and the lid is sealed tightly. The reaction of baking powder produces CO2. The reaction is endothermic.
3 NaHCO3 + NaAl(SO4)2 → Al(OH)3 + 2 Na2SO4 + 3 CO2
What are 2 things you can do to produce more carbon dioxide?
• You can add any chemical to the bottle
•increase or decrease the pressure in the bottle
•increase or decrease the temperature.
To produce more carbon dioxide, you can:
1. Increase the temperature inside the bottle to provide more energy for the reaction to occur faster.
2. Add a catalyst, such as vinegar or lemon juice, to the bottle to speed up the reaction and produce more carbon dioxide.
