To start this laboratory experiment, we first collected all the materials necessary including multiple beakers, samples of each solution, metal strips, a salt bridge, alligator clips, and an abrasive sponge. Then 10 mL of CuSO4(aq) and 10 mL of ZnSO4(aq) were placed into separate 250 mL beakers. A copper strip was then placed in the beaker containing CuSO4(aq) and a zinc strip was placed into the beaker with ZnSO4(aq). The two beakers were connected by a salt bridge that consisted of a string soaked in 0.5 M KI solution and each end was placed into each solution.
Next, the alligator clips of the voltmeter were attached to the strips of metal. The black clip was connected to the zinc strip and the red clip was connected to the copper strip. The voltage was recorded using LoggerPro. The clips and metals were removed from the solutions and cleaned. An abrasive pad and DI water was used to wash them. …show more content…
The CuSO4(aq) solution was then diluted to 0.4 M by placing 8 mL of the solution and 2 mL of DI water into the beaker. The metal strips were reconnected to their respectful alligator clips and the voltage was recorded once more. The dilutions were repeated using 0.3 M, 0.2 M, and 0.1 M CuSO4(aq) , each time being cleaned before replaced. The metal strips were cleaned again and the beaker solutions were recreated using the another 10 mL of each solution. The same process of recording the voltage and changing the molarity was completed, this time using the ZnSO4(aq) solution at molarities 0.5 M, 0.4 M, 0.3 M, 0.2 M, and 0.1
