The document describes an investigation into whether sodium bicarbonate and citric acid react with water, what happens if they do react, and how to capture any gas produced. It asks how much of each substance was used in the reaction bottle and stock solution, noting that one spoonful of citric acid was added to 100mL of water to make 20 samples of 5mL each.

1. Investigation 3: Particles Capture the Gas

2. Will NaHCO 3 react with water?

4. Will C 6 H 8 O 7 react with water?

6. What will happen?

10. How will you capture the gas?

14. How much sodium bicarbonate was in the reaction bottle? How much citric acid was in the reaction bottle?

16. How much citric acid was in the reaction bottle? Yikes! We have to do math in science?
