- Kitchen paper roll
- Straw vinegar
- Bath or large tub/container
Directions for Baking Soda and Vinegar Powered Boat Experiment
- Pierce a hole in the water bottle for the star to go through it. Tape up the gap to prevent any air from escaping the water bottle.
- Pour vinegar into the plastic bottle and then replace the lid.
- Tap some baking soda on a small piece of kitchen roll.
- Stuff the tissue-wrapped baking soda in the bottle and swiftly cover it with the lid.
- Place the plastic bottle in the water and just watch it zoom away.
Baking Soda and Vinegar Reaction
So, what exactly happens with a baking soda and vinegar reaction? Mixing vinegar (acetic acid) and baking soda (sodium bicarbonate) together cause a chemical reaction that makes salt (sodium acetate), water, and carbon dioxide gas. These experiments are exciting for students to do.
There are two separate reactions when baking soda and vinegar mix. There is an acid base reaction and a decomposition reaction.
Acid-based reaction – Hydrogen ions and vinegar react with the sodium and bicarbonate ions that are in baking soda. The result is two chemicals called carbonic acid and sodium acetate.
Decomposition reaction – The carbonic acid and sodium acetate from the acid-based reaction decompose into water (H2O) and carbon dioxide gas.
Baking Soda And Vinegar Science Experiments FAQ
Here are some common questions people ask when mixing baking soda and vinegar.
What happens when you mix baking soda and vinegar and water?
Mixing baking soda and vinegar and water produces carbon dioxide gas which forms bubbles in the foaming mixture. It forms a fizzing reaction of carbon dioxide that consequently is awesome for cleaning and freshening sinks and drains.
What happens if you mix baking soda vinegar and food coloring?
It is important to listen in when mixing the baking soda vinegar and food coloring to hear the fizz. Mixing these three items develops a fizzy foam full of food coloring colors. Make a rainbow or use your young scientist’s favorite colors for a super cool colourful chemical reaction science experiment.
What science experiments can you do with baking soda?
