Curt kim, jonathan lee, keshav mantha, bobbie sheng. Goal: to determine the level of entropy and the thermochemical relationship of three chemical reactions. Procedure: in part a of this experiment, 100ml of distilled water was poured into a styrofoam cup placed inside another plastic cup, and the initial temperature of the water was recorded. Seven sodium hydroxide pellets were massed and added to the water; this mixture was then stirred and the highest temperature it reached was recorded as well. After the final mixture was disposed of, 50. 0ml of 1. 0m hydrochloric acid was poured into the styrofoam cup to conduct. Once the initial temperature was recorded, 50ml of 1. 0m sodium hydroxide was added and stirred, and the highest temperature was measured as well. To carry out part c of the experiment, 100. 0ml of 0. 5m hydrochloric acid was added to the styrofoam cup and starting temperature was taken. Once again, seven naoh pellets were stirred into the acid solution.
