Soda has carbon dioxide gas dissolved in it. In the closed bottle, the soda is under pressure, and so the gas cannot escape. When you open the bottle, you release the pressure and the gas begins to escape -- you can see the bubbles rising. That is what makes the pop-fizz sound. If you leave the bottle open for a while, all the gas will escape and the soda goes flat. If you seal it back up, then the pressure builds back up inside, and keeps the gas dissolved in the soda, so it stays fizzy.

The bubbles are caused by carbon dioxide, which was dissolved in the drink, from leaving solution to the atmosphere. This is how they become flat, and it is due to the equilibrium involved in the "reaction" between carbon dioxide gas and carbon dioxide solute.

Carbonated Beverages get their fizz from the gas carbon dioxide. When the bottle is capped, carbon dioxide dissolves within the soda from the pressure exerted on it. It also occupies the void between the surface of the liquid and the cap. Shaking the bottle adds energy and causes gas in the soda to separate, forming tiny bubbles throughout the liquid. Formation of the bubbles increases pressure inside the bottle. Quickly removing the cap releases this pressure, and the bubbles immediately expand. Forced up the narrow neck, the fluid and bubbles burst from the high-pressure environment of the bottle to the lower pressure of the atmosphere.

Carbonated beverages get their name from the carbon dioxide dissolved in the beverage. Most gases will dissolve in water (which is the main component of soda) but carbon dioxide is particularly good at dissolving and it adds a nice slightly sour taste to the beverage. It may also be added to make it reminiscent of the carbonation found in fermented beverages.

When soda is bottled, it is mixed with carbon dioxide under a little bit of pressure to get the gas to dissolve into it. When you open the container of soda, the dissolved carbon dioxide starts to come out of solution because the air pressure is less than the pressure that was used to get the carbon dioxide to dissolve into the soda.

You actually see the same effect when you put a pot of water on the stove and start to heat it up. The first bubbles you see starting to form at the bottom of the pot are air bubbles from the air that was dissolved into the water which start to come out of solution long before the water gets hot enough to boil and form bubbles of water vapor. In this case it is the change in temperature that gets the gas to come out of solution instead of the change in pressure that makes the bubbles form in soda, but in both cases it is just a dissolved gas coming out of solution.

Since the equation for the equilibrium reaction for the brewing of carbonated beverages and the transport of gases in the blood is: H2O + CO2 <---> H2CO3 <---> H+ + HCO3- then the bubbles in carbonated beverages come from carbonic acid (H2CO3) converting into water (H2O) and carbon dioxide (CO2), in which the carbon dioxide separates as a gas since it is poorly soluble in water.

The bubbles in Coca-Cola and similar sodas are carbon dioxide. It is created by dissolving the gas into the soda under pressure, so that once out of the container (bottle or can), it begins to come out of solution. Both the taste of the gas (as weak carbonic acid) and the action of the bubbles (effervescence) are designed to offset the very sweet taste of the drinks -- sodas can contain more than 12 teaspoons of sugar in a 12 fluid ounce serving.

What is the chemical reaction of water and baking soda?

When water and baking soda are stirred together, bubbles will form. These bubbles are carbon dioxide.


Where does fizz in soda come from?

The fizz in soda is carbon dioxide bubbles. Carbon dioxide is dissolved in the soda by putting it under pressure. When the pressure is released because you open the bottle or can, the carbon dioxide comes out of solution in the form of bubbles. Voila, fizz!

Why do Mentos and soda create a geyser?

Noothing is smooth, everything has little "potholes", although they are minisclue and not visible. Mentos have a lot of these little holes in them, where air can get trapped. When dropping a mento into a soda, the air bubbles release, this causes some bubbles to form and exit the bottle. The roughness of the candy also reacts with the gas in the soda, forming more bubbles that are trying to get the the surface. These bubbles form the "geyser".

No, but it depends on what kind of bubbles you are trying to make. Soap bubbles aren't made out of water and baking soda. You can add baking soda to vinegar and create bubbles, as you've seen in fake volcanoes.
