To figure out if all sodas have the same types of carbonated pH.
I think they all have the same types of carbonated pH.
While conducting this experiment, I first drank a portion of all the soda I had selected. They all had a acidy taste to them. While trying to test the pH, I tried to differ from the acidy taste. Some, were less than others. So I did some research. I seemed very lost there, so I looked on the back of each can, and saw that, on every can there were different percentages. So I then put each soda pop into a bottle, put on my safety goggles, and shook the bottle. Acid is normally really fizzy, so you should be able to differ from there. After I was done shaking, they all seemed to fizzle up less and more than others. They also settled down faster or slower than others.
Sprite had a pH level of 3.29, Mountain Dew had a pH level of 3.27, Coca-Cola had a pH level of 2.52, Dr. Pepper had a pH level of 3.6, and Pepsi had a pH level of 2.61.
Even though all sodas may look the same or taste the same, not all of the same things consist in them. My tested hypothesis goes to show that I however was incorrect. All sodas do not have the same pH level.
