Comparison Of Baking Soda And Vinegar

Baking soda and vinegar together is a chemical change. Evidence of this change is it rises up, a gas is produced, you can hear a sizzle sound, and produces a white foam. The chemical property is chemical reactivity. The types of matter that are reacting are baking soda (NAHCO3) and vinegar (CH3COOH). How much baking soda, added to 10mL of vinegar, will cause a film canister rocket to shoot the farthest? My hypothesis was 7mL of baking soda would shoot the lid farthest. I thought this because if there was too much of baking soda, it would slow down, and if there’s only a little it would barely have a reaction. The independent variable was the amount of baking soda. The dependent variable was how far the lid shot.
Materials:
• Film canister
• Paper towel
• Baking soda
• Vinegar
• Goggles
• Measuring tools

Methods:
1. Measure and cut paper towels (10cm by 12cm)
2. Put 10mL of vinegar in canister
3.

The first launch went 500cm and I had to flick it off with my nail. I had to do that because it was leaking. The second launch went 500cm it went the same distance as the first launch but didn’t have to flick it off with my nail. The last launch went 568cm and it hit the cabinet. The average launch distance for 3mL of baking soda was 522.7cm. During trial B, I used 7mL of baking soda. The first launch went 551cm, the canister took about 5 seconds to pop off. Launch two went 65cm, because it wouldn’t pop off so I flicked it off with my nail. Launch three went 493cm, and it only took about 3 seconds to pop off. The average launch of trial B was 369.7cm. In trial C, I used 14mL of baking soda. For the first launch the lid canister lid went 400cm. When it shot the lid hit the table. The second launch went 376cm, it started sizzling and the lid popped out then hit the table. The final launch went 500cm. The lid canister went past the table and hit the floor. The average distance was 425.3cm.
