The results of this are in the tables below: Electrode-1 AMass before (g) Mass after (g) Mass change (g) Anode 1.381. 30-0.08 Cathode 1.351. 65+0.30 This was done for 10 minutes. The mass lost at the anode should equal the mass gained at the cathode, which this doesn't, it has a percentage inaccuracy of 0.22. 30100 = 73% which is very inaccurate, This may be due to the current being too high, so the coppe...
