Making Manganese Metal

I synthesise a small quantity of manganese metal from manganese sulfate by electrolysis. Despite the simplicity of the idea, generating manganese metal through aqueous electrolysis has a few barriers, mainly the fact that the reduction potential of manganese is much lower than that for water, and thus the electrolysis process will always favour the production of hydrogen over manganese. To get around this, we set up a divided cell to electrolyse our manganese salt, and succeed in making a small amount of metal over the course of 24 hours.
