Discussion The purpose of part A in this experiment was to see what soluble salts and acids conductivity was. The weak electrolytes consisted of .01M acetic acid, .01M ethanol, and .01M sucrose. The strong electrolytes were .01Mpotassium nitrate, .01M copper nitrate, .01M hydrochloric acid, and .01M phosphoric acid. All three soluble salts were strong electrolytes because of their solubility. Two acids were strong electrolytes showing they are more soluble than the acetic acid. Sources of error could have resulted in transferring the solid material from the scale to the beaker causing the molarity to be off and ultimately the conductivity of the solution. The purpose of part B of this experiment was to run a series of chemical 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....
