When conducting the experiment it was obvious to assume that when mixing the same solutions to each other that there would be no reaction. This hypothesis was correct. On each sample when mixing the same solutions to each other no reaction appeared. When placing solution A into solution B, my partners and I noticed that the color had changed to a sky light blue. The same reaction happened to solution A when placing solution B into the mix, the color changed to a sky light blue color. So I assumed that the same reactions would appear when mixing the same solutions in different orders. My hypothesis was correct for the example mentioned above and for most of the solutions results when comparing except for a few exceptions. Those being solutions; D & E, and D & B. When placing solution E into D we noticed the color get a bit darker but when placing D into E we noticed not only the color get a bit darker but as well a few bubbles appeared. When solution D was present in the well and as a group when we placed solution B we noticed the color change from light yellow to cloudy yellow. But, when we placed solution D into solution B the color changed from the color changed from clear to a more “cloudy” color.
When the unknown solution was placed into the rest of the solutions the following were what we noticed as a group; No reaction for A, B, C, E, and the unknown. When the unknown was placed into solution D the reaction was that the color became a little darker. When solution A was placed into the unknown the color went from clear to a light yellow. When solution B was put into the unknown there was no reaction the same for C, E, and the unknown. When solution D was placed into the unknown solution the color changed from clear to a light yellow.
The unknown solution was mostly similar to solution E for the following reasons. The reactions were identical when the solutions E and the unknown were placed into the rest of the solutions. The most clear hint was the fact that they both had the same no reactions in A, B C, and E. When solution A was placed into the unknown the color went from clear to a light yellow. When solution B was put into the unknown there was no reaction the same for C, E, and the unknown. When solution D was placed into the unknown solution the color changed from clear to a light yellow. So it is obvious to say that the unknown is in fact solution E.
