You've already seen what happens when Coca-Cola is boiled.
Now, a widely-circulated video on the Internet Friday, shows a new reaction: this time, what takes place when the popular soft drink is mixed with milk.
After 5 Minutes
After 15 Minutes
After 20 Minutes
After 35 Minutes
After 1 Hour
Viewers responded in a variety of ways, mostly fascinated by what happened.
"Incredible," one wrote.
"This looks disgusting," said another.
The producer of the video offered a scientific explanation for the chemical reaction:
It is a reaction of the Phosphoric Acid contained in the coca cola to the milk. Phosphoric Acid molecules attach to the milk giving them more density and separate out while the remaining liquid that makes up the milk and cocoa cola now being lighter floats on top. The solid matter is basically milk that has been curdled by the addition of the more acidic soda.
Both items are acidic but coca-cola more so. In general, coca-cola has a pH of anywhere from 2.5-4.5 because of the Phosphoric Acid content where milk has a normal pH around 6.7 (almost neutral, milk that is in the base range is usually mastitic).
