Sieve tube "slime" is probably fibrillar as suggested by other workers. The granular material seen in electron micrographs of sieve tubes "fixed" with potassium permanganate is mostly a precipitate ...

This article describes research to quantify the kinetics of Mn(II) and Fe(II) oxidation by potassium permanganate and chlorine dioxide; illustrates the effects of reduced metal ion concentration, pH, ...

Addition of a liquid to a crystalline substance produces smoke an intense violet flames. Set up a heat resistant mat next to an operating vent in the bench top. Add 10 to 15 drops of glycerol to the ...

Graphene, a two-dimensional lattice of carbon atoms, has attracted enormous interest from a broad base of the research community for more than one decade. Graphene nanoribbons (GNRs), narrow strips of ...

Potassium permanganate is a common chemical compound that combines manganese oxide ore with potassium hydroxide. It’s used to treat fungal infections of the skin like infected eczema and athlete’s ...

The intense colors shown in this photo are formed by the exothermic oxidation of ethanol with potassium permanganate in the presence of concentrated sulfuric acid. Murilo Sérgio da Silva Julião is a ...

An interesting phenomenon has been recorded during an investigation in which the test for decomposable organic matter, by the determination of the amount of oxygen absorbed by N/80 potassium ...

POTASSIUM permanganate (1 per cent solution, containing 2 per cent sodium carbonate) has been recommended 1 as a spraying reagent for detecting carbohydrates on paper chromatograms. When testing this ...
