Apr 10, 2022 If you can't get pure nickel (too expensive?), try pricing platinum electrodes, a proper power supply, good pH meter, fume hood, magnetic stirrer/hotplate, etc. Also, it's a bit difficult to dissolve Cu-Ni alloys. Analysts use a solution of sulfuric and nitric acids to dissolve the metal, after which remaining nitric is evaporated off by heating.
