The Strange Chemical Reaction Of Coca Cola Milk Experiment

Coca cola and milk are two of the most commonly drunk beverages around the world. But what happens when they are combined? In fact, the coca cola milk experiment has some strange chemical reactions.

After an hour the liquid in the bottle, after the mix of the two beverages, when the phosphoric acid moleculs come into contact with the milk, the change and as a result they become more dense, separating them from the rest of the liquid. But how this separation is produced? This is mainly because of the reaction of the phosphoric acid with milk, which contains the protein casein.

After 15 minutes, an unusual reaction takes place; when the molecules of the phosphoric acid that contained in coca cola binds to the molecules of milk, giving them more density. Then, the milk starts curdling and becomes a solid compound, that sinks to the bottom of the bottle. The non-affected molecules, on the ohter hand, remain light and clear and begin to float on the top. The hydrogen from the phosphoric acid molecules is released as gas. In fact, the acid of coca cola curdles milk so quickly, that can be seen even with naked eyes. If that’s what this soft beverage does to milk, we can even imagine what can do to the human body.

Even though both beverages are acidic, coca cola has more tha milk. In general, coca cola has a pH from 2.3-4.5, because of its content of phosphoric acid, whereas mile has a normal pH of 6.7.
