Investigating Acid-Carbonate Reactions

Background Information

Key Forumula

Acid + Carbonate → Salt + $C{O}_2$ + $H_{2}O$

Experiment

• Aim
  • To investigate the reaction between vinegar (acid) and bi-carbonate soda (carbonate).
• Hypothesis
  • If vinegar and bicarbonate soda react, then salt, carbon dioxide, and water are produced.
• Risk Assessment

Risk	Hazard	Control
Acids	Burns	Care
Glass	Shattering	Safe Distance
Balloon	Explosion	Safe Handling

• Materials
  • Bi-Carb Soda
  • Vinegar
  • Balloons
  • Zip-Lock Bag
  • Conical Flask
  • Limewater
  • Straws
• Method
  1. Pour $\frac{1}{2}$ tsp of bi-carb soda in balloon
  2. Pour vinegar in conical flask
  3. Attach bi-carb soda balloon
  4. Flip the balloon to pour bi-carb soda in vinegar conical flask
  5. Observe reaction
  6. Pour limewater in measuring cylinder
  7. Pour vinegar in zip-lock bag
  8. Place straw in zip-lock bag and attach to measuring cylinder
  9. Pour bi-carb soda in zip lock
  10. Observe results
• Results
  • Observation 1
    • Acid + Carbonate Reaction = Success
    • Balloon inflated from $C{O}_2$ product
    • Solution fizzed then gradually reduced in intensity
  • Observation 2
    • Failed, spilled vinegar
    • Reaction was successful
