Why does a balloon expand with baking soda and vinegar?

How do you inflate a balloon with baking soda and vinegar?

Use the funnel to pour vinegar into the water bottle, filling about ⅓ of the bottle. Cover the top of the bottle with the bottom of the balloon. When ready, lift the balloon and let the ARM & HAMMER Baking Soda fall into the vinegar. Watch as the mixture fizzes, bubbles, and inflates your balloon!

What is the conclusion of mixing baking soda and vinegar?

The experiment and result of it supported our hypothesis that the bubbles would float on top of the mixture of the baking soda and vinegar. It did this because when we combined the baking soda and vinegar it had a chemical reaction that produces carbon dioxide gas.

What causes the balloon to inflate?

Air molecules collide into the balloon with the same energy inside and outside the balloon. When the bottle is heated, the air molecules inside start moving faster. These molecules now collide into the balloon with more energy resulting in increased pressure. The increased pressure causes the balloon to expand.

Why does vinegar and baking soda react?

They react because one is a base while the other is an acid. … In our case, baking soda is sodium bicarbonate (a base) and vinegar is diluted acetic acid. When they react to release the OH and H to become water, they also release carbon dioxide.

How does baking soda and vinegar make carbon dioxide?

Add 2 tablespoons of baking soda into the soda bottle slowly using your funnel. The baking soda and vinegar will fizz. The gas being given off is carbon dioxide. Keep adding the baking soda until there is no more fizzing.

What is the significance of the increasing size of the balloon after the chemical reaction?

Both changes occur because new substances are created during the chemical reaction. The size of the balloon gives an estimate of the amount of gas produced in the reaction. If you want a bigger balloon you should use more baking soda and vinegar because then more carbon dioxide gas will be produced.

Does the mass change when vinegar reacts with baking soda?

The mass remains the same before the reaction and after. A chemical reaction takes place when vinegar and baking soda are mixed. … If the carbon dioxide gas is contained, the mass of the substances will stay the same according to the Law of Conservation of Mass. If the gas is allowed to escape, the mass will be less.
