Question

Your friend wants to run a STEM experiment to trigger interest in Science. She comes to you for ideas and you suggests the Volcano reaction your professor talked about in class. As you are re-visiting the design with her, you get intrigued how you could track the gas formed.

• Write the chemical reaction in volcano reaction.
• Assuming that your friend will not have glassware, you use in the lab , P=1 atm, temperature=25 oC, design an experiment to measure the volume of gas produced. If you wanted to collect 0.5L of CO2, how much baking soda would you need assuming the Arm and Hammer brand of baking soda is 100% pure?
