Abstract or Description

Did you know that, during a period of 15 to 20-minutes adding milk can change the entire substance of soda. With this project, I am making society aware of the damage a simple soda can do to your body. My approach is to use a variety of different sodas and milks to see how they would react differently to each other. I observed the 

 milk and soda come together and sink to the bottom leaving a clear substance. As a result, the protein in milk attached to the acid in the soda causing it to curdle resulting in a chemical change. Drinking a soda can cause the acids in soda to decrease the proteins in your bones. The chemical change is the phosphoric acid in the soda reacting to the calcium in the milk to make two new products: tricalcium phosphate and hydrogen. In conclusion, I learned that when the phosphoric acid molecules meet the milk, they change, and become denser, separating out and sinking to the bottom as a solid precipitate of curdled milk. Meanwhile, the rest of the milk and soda mixture becomes less dense so it is lighter, and it will float to the top.
