Disadvantages of using potassium permanganate (VII) in volumetric analysis

• Manganate (VII) cannot be used as a primary standard because
• it cannot be obtained in pure form. The impurities are MnO₂.
•  Aqueous solutions of manganese (VII) is unstable and slowly deposit brown manganese (IV) oxide on standing.
•  Hydrochloric acid cannot be used as an oxidizing agent of potassium permanganate VII
•  Nitric acid cannot be used to oxidize potassium permanganate (VII) solution because it is an oxidizing agent
