Testing manganese metal
About 3 months ago I made "manganese metal" using manganese dioxide thermite.
I am wondering if there is anyway to test if it's actually manganese metal.
I reacted it with dilute Sulfuric acid(with a ph of 2) and I had to boil the solution to get it to react and it reacted super slow(about the speed of
iron and hot HCl)

The usual tests for the presence of Manganese (as Mn2+) are to acidify the solution with dilute sulphuric acid. Add either Periodic acid or a
persulphate and warm (The latter may need a trace of silver ion (Ag+) to work). If Mn2+ is present it will be oxidised to purple permanganate. Note
that this is a test for Mn in solution and if the "metal" has any manganese oxide contamination it will also give a positive reaction.
If you're not part of the solution, you're part of the precipitate.
