What is the control variable in a baking soda and vinegar experiment?
The amount of vinegar that you would combine with the varying amounts of baking soda would be the control variable .
Will baking soda and vinegar make a balloon float?
The vinegar and the baking soda mix together to make an acid-base reaction. The reaction creates carbon dioxide gas that bubbles up from the mixture. The gas expands up and out of the bottle and inflates the balloon . (So no, these balloons definitely don’t float !)
Is Vinegar an independent variable?
The amount of vinegar is the independent variable you are testing.
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.
How do you make a balloon fly without helium?
How To Make A Floating Balloon Without Helium Take a bottle and fill it the mixture of Sodium hydroxide and aluminum. Add water inside the bottle. Now its time to attach a balloon to the top of this bottle containing the mixture that we just mentioned here.
Does baking soda and vinegar make helium?
Pour two teaspoons of baking soda into your balloon, and pour half a cup of acetic acid into the bottle. An intense reaction will begin, releasing CO2 and making the balloon inflate. If the reaction is too weak to inflate the balloon, add more vinegar and baking soda , but don’t shake the solution.
How do you make balloons rise without helium?
First, fill the water bottle about 1/3 of the way full with white vinegar. Next, put baking soda into the un-inflated balloon , filling it about halfway. Ideally, you’d have a funnel handy for this process but, because I didn’t have one, I made one out of construction paper rolled up, and tape. It did the trick!
How do you make homemade helium?
What to do : use a funnel to pour vinegar into your bottle (need to fill about 1/3 of the bottle). Pour baking soda into your balloon (fill the balloon approx. 1/2 way). Cover the top of the bottle and lift your balloon and let the baking soda fall into the vinegar.
What causes a balloon to inflate with baking soda and vinegar?
a. When baking soda and vinegar are mixed together, it creates a gas called carbon dioxide. The gas begins to expand in the bottle and starts to inflate the balloon . The more gas that is created, the larger the balloon will inflate .
Is it dangerous to mix vinegar and baking soda?
Nothing dangerous happens when you mix baking soda and vinegar , but basically they neutralize each other and you lose all the beneficial aspects of the two ingredients.
What does the independent variable mean?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable .
Is baking soda soluble in vinegar?
The acid and base in the dry tablet do not react (or react so slowly that evolution of gas is not observed). No reaction is observed when water is added to baking soda . The solid dissolves in water, but no CO2 bubbles form. Baking soda dissolves and reacts with the acetic acid in vinegar to produce CO2 bubbles.
Why does baking soda and vinegar?
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. This makes the reaction bubble and expand, just like when you shake up a can of soda and open it!
