Chemicals all perform different reactions when dissolving into different chemicals, and in the lab “Our First Lab” my group and I observed one of these chemical reactions. The purpose of the lab was to witness the chemistry behind these reactions in action, so we could put research and observations together on how it was possible for something to illuminate with only a forced bend to it. Observed how each light sticks glow depended on the temperature they were exposed to, which had a large effect on the intensity of the glow . For having done my research and acquired some knowledge on this particular phenomenon, I gathered to guess that if a light stick is cracked In the presence of room temperature it will then glow …show more content…
This experiment directly related to class being that it is based on solubility, showing what happens when 2 particular chemicals dissolve in each other. The light sticks we experimented with contained 2 particular chemicals that produced an interesting reaction of giving off energy in the form of light when they mixed. The experimental procedures included observed reactions of when we activated the light sticks, what happens when they are exposed to high and low temperatures, and observed glow intensity of the light sticks being exposed to the high and low temperatures over a 24 hour period. Various clever techniques were carried out for proper temperature exposure to these light sticks, with effects being easily observed. Water baths at different temperatures were used to observe the change in the light sticks, and then a car and fridge to observe the change over time. A light stick is a flexible plastic tube that contains 2 chemicals that, when dissolved together, produce a glow. Most glow sticks are filled with hydrogen peroxide + colored dye surrounding a small glass …show more content…
That as well as this graph of the results rates the glow sticks glow intensity from 1-5 in 15 second intervals, with 5 being the highest and 1 being the lowest. Starting when the 3 light sticks were placed in their baths with one being 3C, another 45-75C, and the third at room temperature. When going through the procedures of the experiment there was one problem, out of our three lights sticks only one glowed when it was activated. A problem with a simple solution of switching the two light sticks, in which glowed with a similar intensity as the first upon activation. The graph of the results we recorded when we observed the change in the light sticks explains just that. Every 15 seconds during the procedure we recorded down if we saw any change in the glow for each light stick. Rating it on a 1-5 scale to easily see the difference between the change in the light sticks glow, based off the temperature they were exposed
