oxides, as those of mercury, silver, andgold, may be reduced by heat alone, but the greaternumber require the conjoint action of carbon, which ata high temperature decomposes them, with evolution ofcarbonic oxide. Among powerful reducing agents maybe mentioned the formiates and the cyanide of… … 312 THE METALLIC SULPHIDES. sium, the former acting through the affinity of carbonicoxide for oxygen, and the latter through the affinity ofcarbon and potassium conjointly. The deoxidation ofmetals may also be accomplished by reducing agents,such as phosphorous and sulphurous acids, or by the…
