Hypothesis

Research

Hypothesis

  • Baking soda is sodium bicarbonate

  • Vinegar is a weak acid

  • When the two components are combined they make a strong rising of fizz

  • This is a multistep reaction

  • The sodium bicarbonate mixes with the acid to create carbon dioxide and water

  • I believe that the higher the ratio of vinegar to baking soda the better the result


Materials

Materials

  • Baking soda

  • Vinegar

  • Something to hold mixture in

  • Low gauge for measuring PSI

  • Balloon

  • Measuring spoon


Procedures

Procedures

  • Pressure Method

    • Measure vinegar and baking soda.

    • Pour each into my device and seal them.

    • Shake container to mix vinegar and baking soda.

    • Read psi gauge to measure the amount of pressure.

    • Record pressure observed on log and graph.

    • Repeat for each vinegar / baking soda combination.

  • Volume Method

    • Measure vinegar and baking soda.

    • Pour each into my device and seal them.

    • Shake container to mix vinegar and baking soda.

    • Measure circumference of the balloon with string.

    • Record circumference observed on log and graph.

    • Repeat for each vinegar / baking soda combination.

Balloon Method Balloon Circumference in Millimeters Due to Baking Soda - Vinegar Mixture


Conclusions

Conclusions

  • My hypothesis was that the higher the ratio of vinegar to baking soda the better the result.

  • I tested my hypothesis using two methods.

    • the pressure methods using a pressure gauge

    • the volume method measuring the circumference of a balloon

  • The reactions were the same for both methods.

  • The more baking soda and the more vinegar the greater the reaction and the more gas.

  • In my mind my hypothesis was correct.
