Hi. In class recently, we performed a reaction where we added potassium permanganate solution to a solution of sodium hydroxide, followed by a few grains of glucose. The resulting solution was green for a short time, and then quickly went to an orange colour. Im not very sure about what happened in this reaction. I think that the permanganate ion was reduced to an MnO42- ion, which is the reason for the green colour, but why did it then go orange? And what is the purpose of the glucose? Was it the reducing agent? Thanks in advance, Dan.
