Carbon Dioxide Gas Production
Carbon Dioxide Gas Production is what happens when two substances mix and release carbon dioxide gas, like the fizzing you see when baking soda meets vinegar.
The fizzing in your sink when you pour baking soda down it and add vinegar shows carbon dioxide gas being released. The two substances mix and react, forming a new gas that bubbles up quickly. You can see the bubbles rise and pop at the surface. The same thing happens inside any reaction that produces carbon dioxide gas.
Explaining carbon dioxide gas production by grade level
When you drop baking soda into vinegar, tiny bubbles form right away. Those bubbles are filled with a gas called carbon dioxide. The gas is lighter than the liquid, so the bubbles float up and pop at the top. If you put raisins in the cup, bubbles stick to them and carry them up to the surface like little life jackets.
Projects that explore carbon dioxide gas production
When vinegar meets ground-up food in a test tube, the acid reacts with the food and releases carbon dioxide gas. A balloon stretched over the top of the tube puffs up as the gas collects inside it. Fresh and processed forms of the same food produce different amounts of gas, so some balloons end up wider than others after eight hours of gentle heat.
When baking soda (a base) and vinegar (an acid) meet inside a volcano-shaped container, they react and release carbon dioxide gas. The acid neutralizes the base, and that gas creates the fizzing eruption. Pour vinegar on top of the baking soda and the bubbling and fizzing come from the gas escaping into the air.
When vinegar meets baking soda packed inside a sealed film canister, the two react and release carbon dioxide gas. Pressure builds fast because the gas has nowhere to go. After a few seconds the lid blows off and the canister shoots into the air.
When baking soda and vinegar react in a container of water, they produce carbon dioxide gas. Bubbles stick to small pieces of spaghetti and lift them to the surface. Once a piece reaches the top, the bubbles pop, the spaghetti sinks, and the cycle starts again.
Vinegar and baking soda mix together in the jar and release carbon dioxide gas. That gas forms tiny bubbles on the wrinkled surface of each raisin and carries it upward. Once a raisin reaches the top, the bubbles pop and it sinks again — then the cycle repeats as long as the mixture keeps producing bubbles.
When baking soda and vinegar meet inside a layer of oil, they react and create carbon dioxide gas bubbles. Those bubbles attach to drops of colored water and carry them up through the oil. Colored blobs rise and fall as new bubbles form — showing that a chemical reaction can push one liquid straight through another.
When a fizzing Alka-Seltzer tablet drops into red cabbage juice layered under oil, the tablet reacts with the liquid and releases carbon dioxide gas. The gas forms bubbles that carry colored blobs of cabbage juice up through the oil. Add a small amount of acid or base and the color of those rising blobs changes mid-fizz.
Dropping a fizzing tablet into a bottle of oil and glowing water releases carbon dioxide gas. The gas bubbles attach to droplets of the glowing liquid and push them up through the oil. Turn off the lights and swirling, glowing blobs rise and fall inside the bottle on their own.
When an antacid tablet meets the colored water at the bottom of an oil-filled bottle, it releases carbon dioxide gas. That gas attaches to tiny water droplets and makes them lighter than the surrounding oil, so they float upward through the shimmery glitter. At the top the gas escapes, the droplet gets heavy again, and it sinks back down — repeating as long as the tablet keeps fizzing.
When an Alka-Seltzer tablet drops into colored water at the bottom of an oil-filled bottle, it reacts with the water and releases carbon dioxide gas. That gas attaches to drops of colored water and makes them lighter, so they float up through the oil. At the surface the gas escapes, the blob sinks back down, and the rising and sinking cycle repeats until the tablet dissolves completely.
