Introduction
This science experiment is based on acids and bases reacting together to produce gases. To perform this, we will try to find out whether vegetables like fresh, frozen, and canned mixed with an acid(like vinegar) and base(like baking soda) produce gas or not. We will also find out which one produces the most amount of gas.
Aim
To determine which creates the most gas when fresh, frozen, and canned vegetables get mixed with vinegar (an acid) and soda (a base).
Theory
1. In research, it was found that fresh vegetables produce the most amount of gas.
2. This is because fresh vegetables have natural enzymes. On the other hand, enzymes in canned vegetables and frozen vegetables get changed during the process of canning and freezing.
3. Therefore, we hypothesized that fresh vegetables would produce the most amount of gas.
Requirements
1. Fresh, frozen, and canned corn
2. Fresh, frozen, and canned peas
3. Fresh, frozen, and canned green beans
4. Fresh, frozen, and canned carrot
5. Four 2 liters bottle
6. 2 cups of vinegar for each vegetable
7. ¼ cup of baking soda for each vegetable
8. Food Processor
Procedure
Step 1: Take all the vegetables (canned, frozen, and fresh).
Step 2: Using a food processor, grind them separately.
Step 3: Pour the vegetables into three different 2 liters bottles.
Step 4: After this, you will obtain three bottles filled with frozen vegetables, canned vegetables, and fresh vegetables.
Step 5: Now, add 2 cups of vinegar to each of these bottles.
Step 6: After adding, cap the bottles and leave them for 30 minutes.
Step 7: When 30 minutes have passed, add ¼ cup of baking soda into each bottle.
Step 8: After some moments, you will find bubbles of carbon dioxide will start forming into the solution. Place a round balloon over each of the three bottles.
Step 9: Observe how carbon dioxide fills the balloon.
Step 10: Record your observations.
Canned, Fresh, and Frozen Peas
Observation
1. From the experiment, we saw that the canned vegetables filled the balloon with the most carbon dioxide gas.
2. After taking the average circumference of all three experiments and then converting it into the metric system, we obtained Canned vegetables as 8259.62 cents. cub., Frozen vegetables as 3473.48 cents. cub., Fresh vegetables as 6647.08 cents. cub.
Result
1. We saw that fresh vegetables did not create the most amount of carbon dioxide gas.
2. Due to the presence of preservatives like salt and water in canned vegetables created the most gas.
3. The salts that are present in canned vegetables are sodium and baking soda (sodium bicarbonate). These two salts combined to produce a bigger reaction.
4. Among all three vegetable types, frozen vegetables produced less amount of carbon dioxide gas. This is because freezing stops the formation of molds and bacteria, and as a result, it stops the creation of bigger reactions.
Precaution
1. Do not add more than ¼ cup of baking soda to each bottle.
2. Record your observation carefully.
Conclusion
In this experiment, acids and bases reacting together to produce gases. We added acid and bases to each fresh, frozen, and fresh vegetable to find which one produced the most amount of gas.
VIVA Questions With Answers
Q.1 What was the aim of your experiment?
ANS. We aimed to determine which created the most gas by mixing fresh, frozen, and canned vegetables with vinegar and soda.
Q.2 Which vegetable produced the most amount of gas?
ANS. Canned vegetables produced the most amount of gas because of the presence of preservatives.
Q.3 Which vegetable produced the least amount of gas?
ANS. Frozen vegetables produced less gas because freezing stopped the formation of bacteria and molds.
