We try to electroplate a titanium strip with manganese metal, unsuccessfully.

This project is working towards the ultimate goal of converting manganese sulfate into potassium permanganate. First, we convert the manganese sulfate into manganese metal (this is what we're trying to do here), and then convert the metal into the permanganate form (I've already done this part of the reaction successfully, and the relevant video is linked below).

In trying to plate the manganese onto the titanium, we run into a series of problems:
- If the current is too high, the manganese flakes off.
- If the pH is too low, no manganese plates out.
- If the pH is too high, manganese hydroxide precipitates on the titanium, ruining the plating.
Overall, we aren't able to plate large quantities of manganese.

I fully believe that this is achievable (possibly with some pH buffering and stirring of the catholyte), but I won't be able to work on this any further for a while. This is all I've got at this stage.
