Potassium permanganate: structure and shape of the permanganate ion; extraction from pyrolusite
Oxidising action of KMnO4 in acidic (FeSO4, oxalic acid, KI), basic (KI) and neutral (H2S) media; use in redox titrations
Potassium dichromate: structure and shape of the dichromate ion; extraction from chromite ore
Oxidising action of K2Cr2O7 and its use in titration; interconversion of chromate and dichromate with pH
