Hypothesis: I think that the most concentrated one is the darkest one in both the acids and bases
Variables
Controlled: The five drops we add of the indicator to the acids and bases
Manipulated:The concentration of the acids of the acids and bases
Materials
-safety goggles
-notebook
-Windex
-lime
Procedure
1. add 1 drop of lime then 2 drops 3 drops 7 drops and 20 drops to each small test tube
2. Add 5 drops to each of the test tubes
3. record your observations
4. repeat for the base(windex)
Data analysis Observations:
Acid (lime): The one with the most drops of the acid is the most concentrated after the water is added. The most concentrated one becomes the darkest color after the experiment.
Base (Windex): The one with the most drops of the base added to it is again the most concentrated one, even when the water is added to it. Unlike the acid where the most concentrated one is the darkest here the most concentrated one is the lightest one.
VI. Concept Acquisition (CONCLUSION):
(Marko) Our guiding question ask what is the color of the most concentrated acid and base. I predicted that the most one concentrated is the darkest color. This prediction was only half right, the most concentrated acid is the darkest color of all the acid with water added to it, but bases are different. The most concentrated base is the lightest color, which is interesting, this shows us that bases and acids are different and how there Ph’s are different.
VII. Concept Application (FURTHER INQUIRY):
Marko: Are data is pretty reliable and truth worthy, because we measured the amount of drops we added to each of the test tubes. For next time we could try with more acids and bases to verify, and be sure that acids are darker and bases lighter.
