Surely you long been known for reasonably interesting experiment with the addition of cola candy "Mentos".However, this experience the fantasy of modern chemists are not limited to fans, and on YouTube, a new, no less popular video with the addition of Coca-Cola ... milk.
The taste and color
try, of course, such a "nuclear" mixture as cola and milk, is not recommended.But the colors of the original drink by mixing it with a new ingredient change almost before our eyes.As is known, the acid pH of cola at rates ranging between 2.5 and 4.5.Because of this it can be used for polishing of old coins and even a popular sweet drink clean off dirt from the machine engine.At the level of the milk pH - normal.So what happens if to pour the milk into a Coke?
course of the experiment
- Open a new bottle of soda water with any dark brown.The famous "Coca-Cola" is perfect for this experience, but it is possible to use any other cola different manufacturers.
- Carefully pour the milk with 2% fat content in a bottle with a sweet drink, filling the container to the top.
- Replace the cover and tighten it carefully.
- Now you need a bit of patience.Check looks like cola with milk, at regular intervals of time - for example, every hour or every half hour.
- Witness the amazing chemical experiment.Slowly but surely, the milk settles on the bottom of the bottle and soda water if it becomes invisible.Amazing, is not it?
How it works
course, cola and milk does not become invisible, it just clarified, while the bottom drops out ugly dark brown precipitate.This chemical reaction occurs due to the interaction between the phosphoric acid and milk.Acid molecules bind to molecules of milk and increase their density and thereby separated from the other liquid.The remaining material having a lower density than the new connection is at the top.
options
Experiment "cola with milk" - great fun for the friendly parties, as well as a fascinating scientific experience for children.Steve Spangler, the owner of the blog about the extraordinary chemical experiments, offers a variety of options to try to mix and make your own conclusions.
for its line of experiments Spangler used several kinds of milk and only two varieties of Coke (regular and diet).Curiously, cola and milk in each case behaved roughly the same.The exception was the experience with almond milk - a sweet drink has gained a shade lighter, but did not give such a strong draft and did not justify the lack of audience expectations epic.
There are various ways to change the conditions of the experiment: Cola, mixed with milk, always held a certain chemical reaction.For example, Spangler offers not twist the bottle cap.Without pressure and by using skim milk in a lighter beverage with a stable foam, but no precipitate.Thus, the best results with conventional soda give fat, skimmed milk and soybean, worst - almond milk and heavy cream.
What does this mean
After watching various videos of explosions cola mixed with candy "Mentos" (as well as numerous scenes of the perfect cleansing of copper coins), the majority of consumers no longer trust advertising "Coca-Cola" andWe decided that the favorite drink too much "chemistry."Yes, cola and milk is not added to the desire to drink soda, but all these amateur experiments did not indicate the potential harm of sweet water.Yes, it is possible to clean copper coins.But the same can be done using any sufficiently acidic liquid.You will likely be surprised, but it is best to handle this difficult task grapefruit juice.He not only is harmless - it is very useful to the human body, but chemically greyprutovom juice contains a lot of acid.The "Coca-Cola" This acid is neutralized with plenty of sugar.Therefore, the only danger to the love of sweet soda is the excessive consumption of sugar - the latter often leads to obesity, the development of diabetes and other health problems.
In all other respects the stake is quite safe - do not let the "viral" video to inspire you to false beliefs.
