This time we will do a simple experiment of making a balloon without us having to blow it. These materials can be obtained easily in our homes.

This trial has many who do it, but not wrong if it is explained back so we always remember it.

Theoretical basis

In chemical reactions one or more substances can be converted into new substances. In accordance with this experiment, vinegar (CH₃COOH) is reacted with baking soda (NaHCO3) to produce CO₂3 gas, meaning that there has been a chemical reaction which resulted in the formation of gas by chemical change, because it produced a new kind of substance. This is evidenced through experiments when vinegar and caustic soda are mixed and foam occurs, so that the small balloon becomes large, because CO2 gas is the result of the reaction.

Tools and Materials:

Vinegar
Baking soda
Bottle
Balloon
Funnel
Scissors and Ropes

Ways of Working

Fill the mineral bottle with water vinegar hinga 1/4 the bottle height
Put 1 pack of baking soda into the balloon with the help of the funnel
Without dropping baking soda into the bottle, put the balloon into the bottle's mouth.
Insert the baking soda inside the balloon into the bottle by rocking the balloon
As soon as it is mixed, the gas will emerge from the solution and make the balloon expand without being blown
If it has reached the desired size then tie the balloon and release it from the mouth of the bottle.

Explanation

Acidic acid is acidic, baking soda (NaHCO₃) is a weak base having a carbonate group.

When mixed reaction occurs

CH₃CO₂H + NaHCO₃ ------> CH₃CO₂Na + H₂O + CO₂ (gas)

Gas CO₂ (carbon dioxide) produced will make the balloon expand.

Conclusion

The acid vinegar is acidic, while baking soda is alkaline. If these two elements are mixed, the degree of acidity or PH will be neutral, and when both are mixed in the closed state as the above experiments, then the two mixtures will produce CO₂ or carbon dioxide gas, this gas that causes the balloon to expand itself. You can try it yourself at home, good luck.
