Metals: Al, Bi, Cu, Fe
Electrolyte pH: Basic
All chemicals began as 0.35 M of Metal Nitrate, 0.6M Ammonium Nitrate, and 0.015M HNO3
0.15M Bismuth Nitrate, 23-25ml of Nitric Acid added to solution, 0.6M NH4NO3
DI Filter to create the Bismuth Nitrate and Sodium Hydroxide solution had less than 1MΩ resistivity. A filter with resistivity greater than 1MΩ may provide cleaner results.
