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. WebAction of heat on KMnO 4: KMnO4 when heated to 473 K, readily decomposes giving oxygen. At red heat, potassium permanganate decomposes into potassium manganate (K2MnO3) and oxygen.
