Title: Electrolytic oxidation of Mn2+ to Mn3+
Post by: g1ng3rbr34d_m4n on January 27, 2015, 06:14:18 AM

I am new to electrochemistry, so please bear with me...

I need to know the conditions required to oxidize Mn2+ to Mn3+.  I don't know how to determine whether an acidic or alkaline electrolyte should be used, or how to determine what cathode to use (lead, graphite, silver, etc.). 

Any help is appreciated.

I think this will be difficult, because Manganese will be oxidised easily to Mn⁴⁺ in form of MnO₂ which precipitates in alcaline solution.

From Manganes-III are not much compounds known, like the Oxide, Flouride and Acetate.
