Fizz Inflator Project

Fizz Inflator

We have already performed a Fizz Inflator activity (if you have not performed it, see it here). We have learned that vinegar and baking soda if combined, it will create carbon dioxide and the gas can be used for inflating a balloon.

We have here a few questions to be answered through proper experiment. The questions are:

Project Questions:

  1. Will baking soda gets reacted with liquids other than vinegar such as water, lemon juice, tea, kerosene, or rubbing alcohol?
  2. Is there any difference in the behavior of reaction when vinegar is having difference in temperature?

Things that you need:

  1. Testing glasses (plastic tumblers of equal size and make) – 7
  2. Baking soda
  3. Lab hot plate
  4. Paper cards – 7
  5. Project data card

Procedure:

Step 1: Add 50 ml of liquids each into 5 different plastic glasses (water, lemon juice, tea, kerosene, and rubbing alcohol).

Step 2: Take 2 tbsp of baking soda each into different paper cards

Step 3: With the help of two more friends add the baking sodas from each paper cards into the plastic glasses at one time.

Step 4: See how the baking soda gets reacted with each liquid.

Step 5: Note is you see any difference in the reaction.

Step 6: Now heat some vinegar to 70 OC or 158 oC. Meantime, pour in 50 ml of room temperature vinegar to one of the fresh plastic glasses.

Step 7: Take 2 tbsp of baking soda to each of the two fresh paper cards.

Step 8: Take the 50 ml of the heated vinegar to a fresh plastic glass.

Step 9: Now add the baking soda from paper cards to one each glass at the same time. See if there is a difference in the reaction.

Step 10: Note your observations and give your conclusion. To get a more accurate result, repeat the experiments a few times before concluding.
