Manganese is one of the transition metals with chemical symbol Mn and atomic number 25.
Manganese is a solid and grey metal at normal pressure and temperature, easily oxidizes turning brown its surface, and if its react with acid like hydrochloric acid turn blue due to the reaction and the production of the chloride, like you can see in this picture on the left.
We suggest this element at the purity of 99,9% in a 5 mL glass vial with about 1,5 cm of diameter.
We put about 10 gram of pure Manganese metal inside.
Normally available in 1 day. You can order manganese metal sample below.
