Question

Part 2: Copper Electrolysis 1. Fill the table with the raw data collected from your copper electrolysis Run # Time Initial Anode Mass (g) Final Anode Mass (g) 11.005 Initial Cathode Mass (9) 10.5 Final Cathode Mass (g) 10.995 Current (A) Time (min) 5:00 300 11.5 11.5 5.00 Amps 2.50 A 2 10.762 10.5 11.238 15:00 900 دیا 10.906 10.5 11.094 1.00 A 30:00 1800 11.5 1 2. Calculate the experimental mass loss at the anode and the experimental mass gain at the cathode for each run from question 1. Run # Experimental Experimental Current (A) Time (or Anode Mass Cathode Mass Loss (g) Gain (9) 0.495 5.00 300 0.508 2 0.740 2.50 900 0.738 0.593 1.00 1800 0.609 Show one sample calculation below: 5A x 300 s = 5 (C*S-1)x= 1500 C 1500 C/2 x 96485 = 7.77x10-3 7.77x10-3x65.38 = 0.508g دیا
