Permanganate reaction
WebA redox titration is a titration in which the analyte and titrant react through an oxidation–reduction reaction. As in acid–base titrations, the endpoint of a redox titration is often detected using an indicator. Potassium permanganate (KMnO₄) is a popular titrant because it serves as its own indicator in acidic solution. WebProcedure. Put 2–3 g of potassium manganate (VII) in a small pile on the tin lid standing on the heatproof mat. Make a small hollow in the centre of the pile. Pour about 1 cm 3 of glycerol into the hollow in the pile of potassium manganate (VII). After about 20 seconds (but beware – it can be much longer), the mixture starts to give off steam.

Permanganate(VII) is a strong oxidizer, and similar to perchlorate. It is therefore in common use in qualitative analysis that involves redox reactions ( permanganometry ). According to theory, permanganate is strong enough to oxidize water, but this does not actually happen to any extent. See more A permanganate is a chemical compound containing the manganate(VII) ion, MnO 4, the conjugate base of permanganic acid. Because the manganese atom is in the +7 oxidation state, the permanganate(VII) ion is a strong See more • Ammonium permanganate, NH4MnO4 • Barium permanganate, Ba(MnO4)2 • Calcium permanganate, Ca(MnO4)2 • Potassium permanganate, KMnO4 See more Permanganates can be produced by oxidation of manganese compounds such as manganese chloride or manganese sulfate by strong oxidizing agents, for instance, See more Permanganates(VII) are salts of permanganic acid.

WebPermanganate (VII) is a strong oxidizer, and similar to perchlorate. It is therefore in common use in qualitative analysis that involves redox reactions ( permanganometry ). According to theory, permanganate is strong enough to oxidize water, but this does not actually happen to any extent. Besides this, it is stable. Dilute solutions of KMnO4 convert alkenes into diols. This behaviour is also used as a qualitative test for the presence of double or triple bonds in a molecule, since the reaction decolorizes the initially purple permanganate solution and generates a brown precipitate (MnO2). In this context, it is sometimes called Baeyer's reagent. However, bromine serves better in measuring unsaturation (double or triple bonds) quantitatively, since KMnO4, being a very strong oxidizing agent, can rea…
WebScience Chemistry Potassium permanganate (KMnO4) standard solution is prepared by dissolving 1.58 grams of potassium permanganate salt in 1.0 L of distilled water. Adjustment of this solution is done with sodium oxalate (Na2C204). 12 mL of this solution was spent in the titration of 0.0501 g sodium oxalate in acidic medium.
