This term, we are doing science. This week, we started doing experiments we had to write up a scientific report and when we finished writing our steps we did the experiment. We mixed vinegar and baking soda together to make it fizz, at the end we tasted it.

QUESTION.
|
If we mix vinegar and baking soda will we observe some kind of reaction?
| |
THESIS.
|
Vinegar tastes sour and it is a liquid. Baking soda is a solid,soft white powder and it tastes salty and horrible. They are both food substances but based on their different taste, they must be chemically different. So, if they are mixed together, there might be a chemical reaction.
| |
HYPOTHESIS.
|
We predict that when we mix vinegar with baking soda an observable chemical reaction will occur. We might see and hear and explosion, fire, foaming, bubbles, fizzing or something else. The resulting mixture might look and taste difference in the size of the materials.

EQUIPMENT
AND MATERIALS:
|
Baking soda.
Vinegar.
counter for mixing .
Teaspoon for mixing.
|
PROCEDURE
|
Step 1 pour some vinegar in the container to the depth of about 2cm.
Step 2 use a tae spoon a baking sodas.
Step 3 mix with half a teaspoon.
Step 4 observe and record what happens.
| |
OBSERVATIONS:
|
At step 2 the mixture started to fizz, A fizzing sound was heard, bubbles were seen to appear in the mixture and the materials rose higher in the container.
At step 3, when the materials were mixed, even more bubbles appeared and the volume of the materials in the container rose even higher.
At step 5 when the mixture was tasted, the taste was unpleasant and was similar to baking soda.

ANALYSIS
AND CONCLUSION |
The goal of this experiment was to see if an observable reaction would take place when vinegar and baking soda were mixed together. The result of our experiment proves that our hypothesis was correct. We predicted that there would be an observable reaction, and there was. There was lots of foaming and fizzing happening and bubbles appeared which means a gas must have been produced. A quick check online showed us that the gas was carbon dioxide.
