This lab taught my classmates and I how to speed up and slow down a chemical reaction. During the actual experiment, my partner and I had to accomplish making iodine, hydrogen peroxide, crushed vitamin C, water, and liquid starch, turn into a purple colored liquid. The experiment was simple and consisted of a lot of mixing. We were given specific instructions when we ran our first trial. Every trial after that we were told to change one variable. My partner and I changed the temperature of our water, we heated it up.

We increased the temperature of the water to speed up the chemical reaction, and that is what we graphed. We noticed that the hotter the water was the quicker the reaction would happen. The reason the reaction happened faster was because the molecules in the concoction were moving much faster than before. Our first trial had pretty cool water so the reaction took a bit longer than the other three, it's reaction time took 211 seconds. Our second trial was the fastest because the water was at 83°c, it only took 10 seconds. The third trial the water cooled down a bit so the reaction happened in 38 seconds.
The vitamin C was what turned the Iodine into a crystal clear liquid, which is strange because Iodine is a very dark colored liquid. Once the Iodine was united with liquid starch and hydrogen peroxide, it turned back into its original color. The experiment worked, so we completed it. I think it worked because we mixed the chemicals up so they would be able to combine completely.
Overall, I learned a lot from this basic chemical reaction. I'm looking forward to encountering more experiments.
