This material contains Potassium permanganate (listed as Manganese compounds, n.o.s. [31] Just under 200 years later, London chemist Henry Bollmann Condy had an interest in disinfectants; he found that fusing pyrolusite with sodium hydroxide (NaOH) and dissolving it in water produced a solution with disinfectant properties. Potassium permanganate and sulfuric acid react to produce some ozone, which has a high oxidizing power and rapidly oxidizes the alcohol, causing it to combust. Potassium permanganate, also known as permanganate of potash or Condy's crystals, is a chemical compound consisting of two ions: a potassium ion and a permanganate ion. Potassium permanganate is an inorganic chemical compound.Its chemical formula is K Mn O 4.It contains potassium and permanganate ions.The manganese is in the +7 oxidation state.It is also known as permanganate of potash and Condy's crystals.Potassium permanganate is a strong oxidizing agent, which means it has a tendency to take electrons from other chemicals.
