Unformatted text preview: and see their different results. The three types of chemical reactions observed in this experiment were precipitate reactions, acid/base reactions, and redox reactions. The first three reactions were observed with nothing more than the human eye to figure out what type of reaction they were. After that a pH indicator was used to determine what happens to the pH of each reactant as they are mixed, something the naked eye cannot determine. Since the solutions were already made by the stockroom there were few sources of error. However, since drops of each reactant were delivered by hand, there could have been more of one reactant than the other throwing off the pH and several other variables....
