Surely you have long been aware of an interesting experiment with the addition of Mentos candies to Coke. However, the fantasy of modern amateur chemists is not limited to this experience, and a new, no less popular video appeared in YouTube with the addition of ... milk to Coca-Cola.
On taste and color
Of course, it is not recommended to try such a "nuclear" mixture as cola with milk. But the colors of the original drink when mixed with a new ingredient change almost before our eyes. As you know, the acid level of cola pH varies between 2.5 and 4.5. Thanks to this, it can be used to polish old coins and even clean off dirt from machine engines with a popular sweet drink. In milk, the pH is normal. So what happens if you pour milk into Coca-Cola?
Experiment progress
- Open a new bottle with any dark brown soda water. The famous Coca-Cola is great for this experience, but it is possible to use any other Cola from various manufacturers.
- Gently pour 2% fat milk into the sweet drink bottle, filling the container to the top.
- Replace the cover and tighten it carefully.
- Now you need a little patience. Check what cola and milk look like at regular intervals - for example, every half hour or hourly.
- Become a witness to an amazing chemical experiment. Slowly but surely, the milk settles at the bottom of the bottle, and soda water seems to become invisible. Terrific, isn't it?
How it works
Of course, a cola with milk does not become invisible, it only brightens, while an ugly dark brown precipitate falls to the bottom. This chemical reaction occurs due to the interaction between phosphoric acid and milk. Molecules of acid combine with milk molecules, increasing their density and thereby separating them from other liquids. The remaining substance, which has a lower density than the new compound, is at the top.
Options
The cola with milk experiment is great fun for a friendly party, as well as an exciting scientific experience for children. Steve Spangler, the owner of a blog about extraordinary chemical experiments, offers to try a variety of mixture options and draw your own conclusions.
For his line of experiments, Spangler used several types of milk and only two varieties of cola (regular and diet). It is curious that cola and milk in each case behaved approximately the same. The exception was the experience with almond milk - the sweet drink took on a lighter shade, but did not give such a powerful sediment and did not live up to audience expectations with the absence of epic.
You can change the conditions of the experiment in different ways: cola mixed with milk always undergoes some chemical reaction. So, for example, Spangler suggests not screwing the bottle cap. Without pressure and when using skim milk , a lighter drink with a stable foam, but without sediment, is obtained. Thus, the best results with plain soda water are obtained from fatty, skimmed and soy milk, the worst - almond milk and fat cream.
What is this talking about
After watching a variety of videos about Cola explosions mixed with Mentos candies (as well as numerous stories about the perfect purification of copper coins), most consumers stopped trusting Coca-Cola ads and decided that there was too much “chemistry” in their favorite drink. Yes, cola and milk do not add to the desire to drink soda, but all these amateur experiments do not at all indicate the potential harm of sweet water. Yes, you can clean copper coins with it. But the same thing can be done with any sufficiently acidic liquid. You will most likely be surprised, but grapefruit juice is best suited for this difficult task . It is not only harmless - it is very useful for the human body, but chemically in grapefruit juice contains a lot of acid. In Coca-Cola, this acid is neutralized by a large amount of sugar. Therefore, the only danger of love for sweet soda is excessive consumption of sugar - the latter often leads to obesity, diabetes and other health problems.
In all other respects, the stake is completely safe - do not let the viral video inspire you with false beliefs.
