When an oxide of manganese (P) is fused with KOH in the presence of an oxidising agent and dissolved in water, it gives a dark green solution of compound (Q). Compound (Q) disproportionates in neutral or acidic solution to give purple compound (R). An alkaline solution of compound (R) oxidises potassium iodide solution to a compound (S) and compound (P) is also formed. Compounds P to S are
