The purplish-black color of solid potassium permanganate, and the intensely pink to purple color of its solutions, is caused by its permanganate anion, which gets its color from a strong charge-transfer absorption band caused by excitation of electrons from oxo ligand orbitals to empty orbitals of the manganese(VII) center.
In an acidic solution, permanganate(VII) is reduced to the pale pink manganese(II) (Mn 2+) with an oxidation state of +2. 8 H + + MnO − 4 + 5 e − → Mn 2+ + 4 H 2 O. In a strongly basic or alkaline solution, permanganate(VII) is reduced to the green manganate ion, MnO 2− 4 with an oxidation state of +6. MnO − 4 + e − → MnO 2− 4

Elementary particle; the basic unit of consciousness. Not a constant, but is generated by and gives sentience to animals in a positive feedback loop. The human brain is a focusing mechanism for Dust. The more conscious the entity, the more Dust is around it. Permeates all universes and passes among dimensions. Parker Particles Marvel Comics
One’s biological age, which measures the body’s physiological state, may help predict who is at risk for developing colon polyps, a known risk factor for colorectal cancer.
A 29-year-old man’s debilitating night terrors were the first sign of rare autoimmune disorder that rapidly progressed, landing him in the intensive care unit in a “catatonic state.”

The Frost diagram is also a useful tool for comparing the trends of standard potentials (slope) of acidic and basic solutions. The pure, neutral element transitions to different compounds depending whether the species is in acidic and basic pHs. Though the value and amount of oxidation states remain unchanged, the free energies can vary greatly.
