Deanne and Bo conduct an experiment at school. They put vinegar into a dish, and then they add baking soda to it. Lots of bubbles form as they stir the two substances together. After the bubbling stops, they notice that they no longer smell the distinctive odor of vinegar. Their teacher explains that the atoms making the vinegar and the atoms making the baking soda were recombined to form water, carbon dioxide, and another compound called sodium acetate. (2 points)
The reaction that occurred between vinegar (acetic acid) and baking soda (sodium bicarbonate) is known as a chemical reaction. When these two substances are mixed together, an acid-base reaction takes place. The acetic acid in vinegar is the acid, while the sodium bicarbonate in baking soda is the base.
During the reaction, the hydrogen ions (H+) in the acetic acid combine with the bicarbonate ions (HCO3-) in the baking soda to form carbonic acid (H2CO3). This carbonic acid is unstable and quickly decomposes into water (H2O) and carbon dioxide gas (CO2).
The other compound that is formed is sodium acetate (CH3COONa). The sodium ions (Na+) from the baking soda combine with the acetate ions (CH3COO-) from the acetic acid to form this compound.
As a result of this reaction, the vinegar no longer smells because the acetic acid has been converted into other compounds. Additionally, the formation of carbon dioxide gas is responsible for the bubbling observed during the experiment.
To summarize the provided information:
1. Deanne and Bo added vinegar and baking soda to a dish.
2. When the two substances were stirred together, lots of bubbles formed.
3. After the bubbling stopped, they noticed the vinegar odor was no longer present.
4. Their teacher explained that the atoms in both substances recombined to form water, carbon dioxide, and sodium acetate.
