Experiment #2 – Aqueous Solutions and Solution Stoichiometry Ryan Henry Section 523 Lab Partner: Charlotte McCoy Summary: The purpose of this experiment was to examine the behavior of strong, weak and non- electrolytes by measuring the electrical conductivity of various solutions and also to examine the stoichiometry of an acid base reaction in which a solid precipitate forms. In this experiment, we measured the conductivity values of a list of different solutions using a conductivity probe and a computer with specialized software installed on it. We then obtained 70 mL of Ba(OH) 2 and a burette of H 2 SO 4 . We measured the conductivity of the Ba(OH) 2 solution, then added a small amount of H 2 SO 4 over and over again until the solution reached a conductivity value under 50 µs/cm, then added slightly more of the H 2 SO 4 until the conductivity value was back up to 2,000 µs/cm. During this experiment, we discover which solutions are electrolytes in Part A and in Part B, we determine that the concentration of Ba(OH)
