Baking Soda And Vinegar Lab Report

DOES BAKING SODA AND VINEGAR INFLATE A BALLOON?

INTRODUCTION

This experiment is investigating if baking soda and vinegar will inflate a balloon. Baking soda is a chemical salt that occurs in its natural form as the mineral NaHCO2. NaHCO2 is an amphoteric compound, this means that it would react as an acid and a base. Vinegar is a liquid chemical, which consists of mostly acetic acid and water. CO2 is a gas called carbon dioxide. This gas is a natural occurring compound, which consists of a carbon atom covalently double bonded to two oxygen atoms. This reaction of baking soda and vinegar is a chemistry reaction. This is because the two substances of baking soda and vinegar are both chemicals.

AIM

To determine if changes in amounts of baking

soda and vinegar when mixed will affect the diameter of the balloon.

HYPOTHESIS
If ratios of baking soda and vinegar are changed, then the reaction of the vinegar mixed in with the baking soda will cause the balloon to have a bigger diameter because the more volume the greater reaction.

VARIABLES
DEPENDENT VARIABLES - Time it takes to blow up a balloon and the diameter of the balloon
INDEPENDENT VARIABLES - Amounts of baking soda and vinegar in each bottle
CONTROL VARIABLES - Size of bottles and balloons

MATERIALS
Balloons {x4}
Baking soda
Vinegar
Small funnel {x2}
Small bottle {x4}
Tablespoon
Half a cup
plastic bowl
skewer
budder knife
Small cups {x4}

PROCEDURE
1. Using the funnel, pour one tablespoon baking soda into the balloon if get stuck just use a skewer make the baking soda flow down into the balloon.
2. Using the other funnel, pour half a cup of vinegar into the bottle and place the bottle in the cup.
3. Locate the balloon opening, place the mouth on the nozzle of the bottle, being carful not to release any baking soda from the balloon.
4. Have measurement device and stop watch ready.
5. When ready, lift the balloon up so that all the baking soda is transferred to the bottle containing vinegar.
6. Record the diameter of the inflated balloon.
7. Repeat step 1 - 7 using the different measurements of baking soda and vinegar
in table number 1.

DISCUSSION
Q1. The results of this experiment show that the more amount of baking soda and vinegar will create a bigger reaction. In table two the results show that Experiment number 1 had the smallest reaction. Experiment number 1's diameter had reached up to 44 cm. This is because there was a error in sealing the balloon on the nozzle of the bottle. The highest reaction was Experiment number 3 because the diameter reached up to 59 cm. This is because there was a greater amount of baking soda and vinegar in the bottle, which created the biggest reaction.

Q2. The results of this experiment are supported by the hypothesis. This is because the greater ratio of baking soda and vinegar, which will create a bigger reaction. Vinegar has 3% acetic acid and then 97% is water and baking soda is known as sodium bicarbonate. When the baking soda meets the vinegar it created a gas then the gas heats up because sodium acetic is a dry gas which emit heat. If a gas is heated it will rise and that is why the balloon had blew up. The gas that vinegar and baking soda made and carbon dioxide was heated then it rose which blew up the balloon.

Q3. When the experiment was started it was discovered the original amounts of baking soda and vinegar was insufficient. This can be classified as an error and a way to improve this was to start the experiment again and correct the original amounts of baking soda and vinegar.

CONCLUSION
In this experiment the results have shown that the greater ratio to baking soda and vinegar will give a greater reaction.

In the graph it shows that the bottle with the highest reaction is Experiment number 3 and the lowest reaction was Experiment number 1. The hypothesis and aim are supported by the results because the greater ratio of baking soda and vinegar will create a bigger reaction.
