CHEM 130 Lecture Notes - Galvanic Cell, Cellular Respiration, Concentration Cell
Document Summary
This experiment was performed to determine the behaviors of different solutions in galvanic cells. A salt bridge was connected to the corresponding solutions as they were being tested to allow the transfer of energy. In part two & three, we measured the potential ecell difference between the varying molarities of copper sulfate to understand the trend in energy. After analyzing the data, we were able to calculate the probable molarity of an unknown concentration of copper sulfate. Objective: the purpose of this experiment is to compare the potential cell energy of solutions experimentally and mathematically. Then in the second part, the purpose is to determine an unknown molarity of a solution by using a calibration curve created by various tests. Claim: after computing predicted values and comparing them to experimental values, we can analyze trends and behaviors of galvanic cells.
