Chemistry of Art (Oxidising Strength of KMnO4)

[emanhaik]

My class has begun the chemistry of art module and we have no idea how to approach the dot point : demonstrate and gather first-hand information about the oxidising strength of KMnO4 (potassium permanganate). Our experimental results have not been useful what so ever and we do not know what exactly is required for the dot point (maybe a different experiment). There is little information on this prac from what we have found and when there is it is often convoluted. I have checked out the chemistry of art summaries and it is still quite confusing.
Any help would be greatly appreciated!

its a strong oxidizing agent because elements become more electronegative as the oxidation states of their atoms increase. The permanganate in potassium permanganate has MnO4-, hence KMnO4 is a strong oxidising agent.

heres a link to a bored of studies forum which i cbs copy-pasting from

hope i helped
