Question

permanganate ion in acidic medium reacts with oxalate ion to form divalent manganese ion and carbon dioxide​

Answer 1

Answer:

permanganate is the general name for a chemical compound containing the manganate(VII) ion, (MnO−

4). Because manganese is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent. The ion has tetrahedral geometry.[1] Permanganate solutions are purple in color and are stable in neutral or slightly alkaline media. The exact chemical reaction is dependent upon the organic contaminants present and the oxidant utilized. For example, trichloroethane (C2H3Cl3) is oxidized by permanganate ions to form carbon dioxide (CO2), manganese dioxide (MnO2), hydrogen ions (H+), and chloride ions (Cl−).
