Simple Chemistry Experiment: Balloon Inflates Without Blowing

This practicum aims to determine the chemical reaction between vinegar and baking soda which produces carbon dioxide gas so that it inflates the balloon without blowing it up.

Tools and Materials :

1. Baking Soda
2. Vinegar
3. You C 1000 Bottle
4. Funnel
5. Balloon

 Work Steps :

1. Put the vinegar solution into the bottle.
   
   
   
2.  Put the baking soda into the balloon using a funnel. 
   
   
   
3.  Stretch the mouth of the balloon and insert it into the mouth of the bottle.
   
   
   
4.  Hold the mouth of the balloon with one hand and hold the dangling balloon with one hand and lift the balloon so that the baking soda falls into the bottle.
   
   
   
5. Observe the results. 
   
   
   

Discussion :

When baking soda (NaHCO3) mixes with vinegar (CH3COOH), it will produce lots of air bubbles. These air bubbles are gas produced from mixing baking soda and vinegar. This gas is called carbon dioxide (CO2). Well, this gas enters the balloon so that the balloon can inflate without being blown up. The reaction equation is as follows: NaHCO3 + CH3COOH = NaCH3COO + H20 + CO2The size of the balloon that inflates also depends on the size of the measure of baking soda and vinegar mixed, the larger the measure of both, the bigger the balloon will inflate and/or vice versa.
