The Effect of Molarity, Temperature, and Surface Area on the Voltage Given Off in a Galvanic Cell
This experiment was performed to determine if molarity, temperature, and surface area affected the voltage given off in a galvanic cell. The procedure consisted of finding the voltage given off by each galvanic cell using the eight experiments: 1) high molarity, high temperature, high surface area, 2) high molarity, high temperature, low surface area, 3) high molarity, low temperature, high surface area, 4) high molarity, low temperature, low surface area, 5) low molarity, high temperature, high surface area, 6) low molarity, high temperature, low surface area, 7) low molarity, low temperature, high surface area, and 8) low molarity, low temperature, low surface area. A 3-factor Design of Experiment was performed to find the results of the experiment. The results showed that there were no factors that had any significant affect on the voltage output. The hypothesis stated that if a high molarity solution, high temperature, and high surface area are used, then the highest voltage readings will be reached with the use of a galvanic cell. This hypothesis was rejected because the highest voltage given off besides the standard was under the condition of low molarity, low temperature, and low surface area.
