How much amount of baking soda and vinegar inflate a balloon?

The amount of baking soda (sodium bicarbonate) and vinegar (acetic acid) required to inflate a balloon will vary depending on several factors, such as the size of the balloon, the concentration of the vinegar, and the atmospheric conditions. Here's a general guideline to help you estimate the amounts needed:

1. For a Small Balloon (about 6 inches in diameter):

- Baking soda: 1 teaspoon (approximately 5 grams)

- Vinegar: 1/4 cup (approximately 60 milliliters)

2. For a Medium-Sized Balloon (about 12 inches in diameter):

- Baking soda: 2 teaspoons (approximately 10 grams)

- Vinegar: 1/2 cup (approximately 120 milliliters)

3. For a Large Balloon (about 18 inches in diameter):

- Baking soda: 3 teaspoons (approximately 15 grams)

- Vinegar: 3/4 cup (approximately 180 milliliters)

Instructions:

1. Place a funnel in the mouth of an empty balloon.

2. Pour the baking soda into the balloon through the funnel.

3. Remove the funnel and carefully stretch the neck of the balloon to seal it, keeping the baking soda in.

4. Pour the vinegar into a separate container.

5. Hold the balloon with the baking soda over the container of vinegar.

6. Slowly pour the vinegar into the balloon, allowing it to mix with the baking soda. A chemical reaction will occur, producing carbon dioxide gas, which will inflate the balloon.

7. Continue adding vinegar until the balloon reaches the desired size.

8. Once the balloon is fully inflated, carefully release the gas by holding the neck of the balloon and slowly opening the opening. Caution, gas and liquid can spray out suddenly.

Notes:

- Always conduct this experiment in a well-ventilated area to avoid breathing in excessive amounts of carbon dioxide.

- Vinegar with a higher concentration of acetic acid (usually around 5%) will react faster and produce more gas than lower concentration vinegars.

- The speed at which the balloon inflates will depend on the concentration of vinegar and the temperature of the baking soda and vinegar.

- You may need to adjust the amounts of baking soda and vinegar based on your specific conditions and the size of the balloon.

Remember to wear eye protection when conducting this experiment and be careful not to spill the vinegar or get it in your eyes.
