Electrolysis Prediction I have decided to study the effect of current upon the mass of nickel deposited at the cathode. I think that as you increase the current the mass of nickel deposited at the cathode will increase in proportion. Also that the mass loss at the anode will be equal to the mass gained at the cathode. Obtaining Current (A) Mass of cathode at start (g) Mass of cathode at end (g) Increase in mass of cathode (g) Mass of anode at start (g) Mass of anode at end (g) Decrease in mass at anode (g) 0.2 1.331 1.306 1.340 1.383 1.355 1.390 0.052 0.049 0.050 1.32 1.352 1.347 1.280 1.294 1.293 0.052 0.058 0.054 0.4 1.530 1.501 1.435 1.640 1.594 1.522 0.110 0.093 0.087 1.520 1.461 1.395 1.411 1.345 1.290 0.109 0.116 0.105 0.6 1.475 1.521 1.395 1.620 1.651 1.535 0.145 0.130 0.140 1.520 1.385 1.482 1.326 1.224 1.327 0.194 0.161 0.155 0.8 1.385 1.372 1.435 1.548 1.542 1.604 0.163 0.170 0.169 1.432 1.501 1.395 1.204 1.300 1.180 0.192 0.201 0.215 Any anomalous results I find I will not include in the calculation for the average. I have highlighted any anomalous results.
