- Purpose: I wonder what happens when you mix baking soda and vinegar.
- Hypothesis: I think mixing baking soda and vinegar will create a fizzy reaction that produces gas.
- Materials: Baking soda, white vinegar, a small bowl or cup, a spoon, and a measuring cup.
- Procedure: 1. Pour 1/4 cup of vinegar into the bowl. 2. Add 1 tablespoon of baking soda to the vinegar. 3. Observe what happens immediately after mixing.
- Results: When the baking soda was added to the vinegar, it fizzed vigorously and bubbles formed rapidly. The mixture overflowed slightly from the bowl, and a clear gas was released.
- Conclusion: I learned that mixing baking soda (a base) and vinegar (an acid) causes a chemical reaction that produces carbon dioxide gas, which creates the fizzing and bubbling observed.
