Soda Acidity

Soda Acidity

Discussion

We place sour dough bread in four different soda's for 10 minutes to determine which one reacted the most with the soda. The reaction that we observed helped us determine the which soda was the most acidic of the four different sodas.

Conclusion

Coca-Cola

Mountain Dew

Methods/Procedures

In out experiment we were tying to determine which soda was the most acidic. I hypothesized that Coca-Cola would react the most with the bread then all the other sodas. MY hypothesis was wrong and we observed that Mountain Dew reacted the most with the bread and produced the most amount of fizz.

Variables

Coca-Cola had the second most amount of fizz produced meaning that its chemical reaction wasn't as big or long as Mountain Dew's. After sitting in the soda for 10 minutes it had the texture of a soggy sponge.

Out of all 4 sodas Mountain dew created the most amount of fizz meaning that the was a bigger or longer lasting chemical reaction. Also after sitting in the soda for 10 minutesit had the texture of raw fish.

1) Fill the beaker up with 10 millimeters

of an individual soda.

2) Pour the soda into a clear solo cup

and label each cup.

3) Repeat steps one and two for each

soda.

4)Take a piece of sourdough bread and

cut it in to four equal size squares.

• Independent
• The Soda Brand
• Dependent
• The state of the bread afterwords
• Control
• Amount of soda
• Size and type of container
• size and amount of bread added

Results

Mountain Dew reacted the most based on the amount of fizz that was produced, then Coca-Cola, then Cheerwine, and final Pepsi reacting the least amount.

Conclusion Continued

Our observations also concluded that Coca-Cola was the second most acidic followed by Cheerwine and finally Pepsi. This confused my since both Pepsi and Coca-Cola have the same acids in them. If i was able to redo the experiment i would probable do more trials and have the sodas all at the same temperature.

Pepsi

Cheerwine

What soda is the most Acidic?

Pepsi was the least intresting to watch because it had little fizz meaning there wasn't as much of a chemical reaction going on and after sitting in the soda for 10 minutes it felt like wet paper.

Cheerwine fizzed the second least so the chemical reaction wasn't as big or long as Mountain Dew or Coca-Cola. The bread after sittting in the soda for 10 minutes had the texture closely to tender meat.

Introduction

Methods/Procedures Continued

Mountain Dew contains two acids as ingredients, Citric Acid, and a less know erythorbic acid. Coca Cola only contains one acid, phosphoric acid. Much like Mountain Dew, Pepsi contains Citric acid and phosphoric acid. Cheerwine has the same acids in it as Pepsi.

5) At the same time add the bread to the

sodas and start your timer.

6) Record any observations made right

when you put the bread in.

7) After letting the bread sit in the soda

for ten minutes remove it and place it on a paper towel.

8) Record your data on the graph.
