Read the Voltmeter to see what the electrical cell potential is. Repeat steps 13-18 for all variations of Copper Chloride. Record the raw quantitative data in the table below:

Electrical Potential Difference Between Zinc and Copper Solutions Electrical Potential Difference
Variation in Copper Chloride Trial 1 Trial 2 Trial 3
0.5
1
1.5
2
2.5

Record qualitative data as well in the Observations section. When all quantitative data has been collected and recorded, use the equation below to calculate the average electrical potential difference, or Average E_Cell of each variation of Copper Chloride.

Ave.E_(Cell ) for Variation in Copper Chloride=(Trial 1+Trial 2+Trial 3)/(Number of Trials)

Create a scatter plot graph with a trend line to showcase the data. Calculate the slope/increase in average cell potential with the equation below:

Slope=Rise/Step
=(y_2-y_1)/(x_2-x_1 ) Observations:

Qualitative Observations: Zinc chloride was easier to manipulate than Copper chloride because the solid was less condensed than Copper When Zinc Chloride was mixed with water, the solution was first green and when stirred turned light blue When the Potassium Nitrate became fully dissolved in water, the bottom of the beaker became cold The more Copper Chloride that was added to the Copper solution, the more opaque the solution became When the salt bridge connected the two electrodes, the Voltmeter reacted immediately
