How To Use Manganic acid In A Sentence

All other permanganates, as well as permanganic acid itself, give solutions of the same color. An Elementary Study of Chemistry
Organic acids, ferrous oxide, chromic oxide, ammonium salts, etc., prevent the formation of peroxide and the red color produced by permanganic acid. Scientific American Supplement, No. 441, June 14, 1884.
If a solution of ferric oxide and manganese ammonium oxalate is submitted to electrolysis, without the previous addition of ammonium oxalate, the characteristic color of permanganic acid immediately makes its appearance, and the peroxide gradually precipitates itself on the positive, while the iron is deposited on the negative electrode. Scientific American Supplement, No. 299, September 24, 1881
