Soda is one of the most common drinks around the globe. Everyone seems to love it. Even the picky drinkers have a glass of soda once in a while. However, not many people really talk about it. There are journals and open discussions about fine wines, but not for soda pop. So, here are some facts to pop the soda mysterious bubble:
What is soda?
Soda has a lot of bubbles because of the gas carbon dioxide (also known as CO2) dissolved into the sugary, syrupy liquid. Without this carbon dioxide, your soda pop would be flat and boring. Unfortunately, carbon dioxide molecules tend to leave the soda, popping through its surface and escaping into the air.
Should you put your soda pop in your fridge?
Yes, you should. When your soda is cold, the carbon dioxide molecules have less energy to pop out. That is why cold soda can hold more CO2. The soda you buy cold will be frizzier than the ones just sitting on the shelves. But do not freeze it into ice, though.
How do the manufacturers make soda frizzy?
At the factory, soda bottles will be loaded with a kind of air that contains concentrated carbon dioxide. They may also increase the pressure of this gas. This will make it more difficult for the CO2 to escape, increasing the rate at which these stubborn molecules are returned to the soda.
Why does soda frizz more when it is poured on ice cubes?
The frizz is created by the surface of the ice cubes, not their temperature. It is easier for bubbles to form on rough surfaces than smooth ones. An ice cube dropped into a sparkling soda generates bubbles, not because of its coldness, but because of its surface roughness, which provides more cavitation sites.
The extra soda frizz in a glass full of ice cubes is due to a ‘seeding effect.’ Although the solubility of CO2 is higher in colder soda, the bubble formation is also dependent on gas molecules. The CO2 molecules are far less likely to come back to the polar aqueous environment surrounding the bubble, or the soda, since the attraction between water molecule forces the CO2 out. So, once a bubble started, it will enlarge to a visible size and float to the top.
Soda can be fun to drink, but it contains a pretty high amount of sugar, which is not good for your health. You may have a small glass of soda as an occasional treat, but do not substitute it for plain water.
