Observation of Chemical Changes
Abstract: The objective of Experiment 1 was to observe some chemical changes. While observing the chemical changes in elements I also experimented with household cleaners to see how much chemical properties relate to our daily lives. Chemical changes occur all around me and I go without noticing them all the time without a second thought. This experiment opens my eyes to different chemical reactions occurring around me. This experiment also shows the importance of dilution. If I did not dilute something properly, than I might not be able to see a reaction occur.
Experiment: The first step in this experiment was to dilute HCI, NH3, and NaOH. I placed each chemical in a separate well in the 24 well plate. I then diluted each of those chemicals with 10 drops of water.
After the dilutions were complete, I made a chart like the Lab Assistant showed to keep my data organized.
With the 96 well plate I then began the combination of the chemicals. For each chemical combination I placed 2 drops of one chemical and 2 drops of the next chemical, unless it said otherwise. After each combination I looked at the reactions with a white and black piece of paper underneath the well plate to determine what was happening. Using my chart I wrote down my observations that occurred.
After testing required combinations I chose 3 household cleaners to test. I chose Clorox, Windex, and dish soap and recorded their reactions. Dish soap being the most acidic out of the three.
Calculation and Error: The biggest calculation and error that I can think of, would be the trying to get the same amount of substance for each combination every time. The lab told us to measure in drops when there could be small drops and there could be big drops. Our mixtures were not completely perfect because our drops could not be exactly the same size every time.
Conclusion: In conclusion to this experiment, I learned that dilution and having the proper measurements is important when combing chemicals
