Baking Soda and Vinegar Reactions

By Laura Hospitál on Jul 01, 2016

This science project was done by Mike, who is a student at Texas School for the Blind and Visually Impaired (TSBVI).  

In this experiment the student tested how various vinegars affected the strength of the reaction with baking soda.  He also built a volcano to react the vinegar and baking soda in.

 

Question:

Which vinegar made the reaction last longer with baking soda?  The three types of vinegar used were white vinegar, red wine vinegar, and balsamic vinegar.

Hypothesis:

My hypothesis is that the balsamic vinegar will react the longest.

Materials

  • Measuring spoons 
  • Adapted graduated cylnder
  • red wine vinegar vinegar
  • white vinegar
  • balsamic vinegar 
  • baking soda
  • 3 bowls
  • timer or iPad for timing the reaction

Procedure

  1. Measure 10 mL of baking soda and pour it into the bowl.
  2. Measure 30 mL of vinegar into a measuirng cup.
  3. Pour the 30 mL of vinegar into bowl 1.
  4. Wait until the fizzing sound is completely done and stop the timer.
  5. Record the time.
  6. Repeat steps 1-5 using Red Wine Vinegar into bowl 2.
  7. Repeat steps 1-5 using balsamic vinegar into bowl 3.
  8. Analyze data and draw a conclusion.

 

Data

Vinegar data table showing Balsamic 1.5, red wine 1.42, regular 1.36

 

Conclusion:

My hypothesis was right:  the balsamic vinegar did react the longest and it also made a bigger effect.

Variations

  • This experiment can be done with other types of vinegar.

NGSS Standards:

Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly.
