Permanganate color change
WebAug 21, 2024 · The potassium manganate (VII) solution is usually made mildly alkaline with sodium carbonate solution, and the typical colour changes are: In testing for a C=C double bond Potassium manganate (VII) oxidizes carbon-carbon double bonds, and so goes through the colour changes above. Ethene, for example, is oxidized to ethane-1,2-diol. Potassium permanganate is the potassium salt of the tetrahedral transition metal oxo complex permanganate, in which four O ligands are bound to a manganese(VII) center. KMnO4 forms orthorhombic crystals with constants: a = 910.5 pm, b = 572.0 pm, c = 742.5 pm. The overall motif is similar to that for barium sulfate, with which it forms solid solutions. In the solid (as in solution), each MnO−4 centre is tetrahedral. The Mn–O distances are 1.62 Å.
