Description / Table of Contents: Lösungen von KMnO4 in konz. Phosphorsäure (50 Gew.-%) sind nicht stabil. Das MnVII wird unter Sauerstoffabspaltung in MnIII überführt. Das Ausmaß dieser Zersetzung hängt von der Säurekonzentration ab.

Notes: Solutions of potassium permanganate in concentrated phosphoric acid (above 50%) are found to be unstable. The oxidation state of manganese is reduced from (VII) to (III) and oxygen is evolved during this process. The extent of decomposition of permanganate is found to be dependent on the concentration of the acid.
