WebHowever, ketones can be oxidized to various types of compounds only by using extremely strong oxidizing agents. Typical oxidizing agents for aldehydes include either potassium permanganate (KMnO 4) or potassium dichromate (K 2 Cr 2 O 7) in acid solution and Tollens reagent. Peroxy acids, such as peroxybenzoic acid:
Webpermanganate. Table 1 shows all the different reactions performed, showing the concentrations of both the reductant and the permanganate. Some of the reactions were allowed to react, and then when finished reacting, samples were taken out from the reaction and diluted to a concentration of permanganate in the region of the calibration curve. WebNov 14, 2012 · Be careful because the reaction between sodium bisulfite and potassium permanganate is highly exothermic (heat released). After you have added enough sodium bisulfite to remove the purple color in the reaction flask, you will collect the filtrate using vacuum filtration and a Büchner funnel.
