Hi Eric,
If I recall, Epson Salt is magnesium sulfate (MgSO4). Apparently, the sulfate
ion is being oxidized to something else other than oxygen. Perhaps some
peroxy sulfate ion (S2O8-2) is formed and the reaction is catalyzed by iron.
Usually platinum electrodes are used to prevent interaction with the sulfate
ion. Also the 9 volt battery may be causing side reactions in the solution.
Usually 3 volts is more than enough to produce electrolysis. The reaction at
the anode (sulfate ion) is rather complex.
