Mn exhibits large number of oxidation states in its compounds: Which is the highest oxidation state? Name an industrially important compound you have studied in. which Mn is in its highest oxidation state. How is that compound manufactured?

Explanation

In .(KMnO)_(4)., Mn,exhibits the highest oxidation state of +7.
Potassium permanganate is prepared from pyrolusite, .(MnO)_(2).. Powdered pyrolusite is fused with .(KOH). or .(K)_(2) (CO)_(3).. The molten liquid is stirred well in the presence of air when green coloured potassium magnitude is formed.2 (MnO)_(2)+4 (KOH)+(O)_(2) rarr 2 (~K), (MnO)_(4)+2 (H)_(2) (O).
Potassium manganate is extracted with water and oxidised electrolytically between iron electrodes to potassium permanganate.
.(K)_(2) (MnO)_(4) harpoons 2 (~K)^(*)+(MnO)_(4)^(2-).
At anode : .(MnO)_(4)^(2-)+(e)^(-).
At cathode: .2 (H)^(+)+2 (e)^(-) rarr (H)_(3).
The overall reaction is
.2 (~K)_(2) (MnO)_(4)+(H)_(2) (O)+[(O)] rarr 2 (KMnO)_(4)+2 (KOH).
