Oxidizing silver with liver of sulfur solution. Liver of sulfur is a loosely defined mixture of potassium sulfide, potassium polysulfide, potassium thiosulfate, and likely potassium bisulfide. Synonyms include hepar sulfuris, sulfur, sulfurated potash and sulfurated potassa. There are two distinct varieties: "potassic liver of sulfur" and ...
Liver of sulfur – formed by fusing [clarification needed] potash and sulfur. Lunar caustic/ lapis infernalis – silver nitrate, formed by dissolving silver in aqua fortis and evaporating. Lye – potash in a water solution, formed by leaching wood ashes. Potash – potassium carbonate, formed by evaporating lye; also called salt of tartar. K ...
Some silver oxide powder.. Silver is a relatively unreactive metal, although it can form several compounds. The common oxidation states of silver are (in order of commonness): +1 (the most stable state; for example, silver nitrate, AgNO 3); +2 (highly oxidising; for example, silver(II) fluoride, AgF 2); and even very rarely +3 (extreme oxidising; for example, potassium tetrafluoroargentate(III ...
The exact correlation varied over time, and in early centuries bronze or electrum were sometimes found instead of mercury, or copper for Mars instead of iron; however, gold, silver, and lead had always been associated with the Sun, Moon, and Saturn. [note 1] The associations below are attested from the 7th century and had stabilized by the 15th ...
It constitutes the tarnish that forms over time on silverware and other silver objects. Silver sulfide is insoluble in most solvents, but is degraded by strong acids. Silver sulfide is a network solid made up of silver (electronegativity of 1.98) and sulfur (electronegativity of 2.58) where the bonds have low ionic character (approximately 10%).

For copper alloys, such as bronze, exposure to chlorides leads to green, while sulfur compounds (such as "liver of sulfur") tend to brown. The basic palette for patinas on copper alloys includes chemicals like ammonium sulfide (blue-black), liver of sulfur (brown-black), cupric nitrate (blue-green), and ferric nitrate (yellow-brown). For ...
Traffic on the Massachusetts Turnpike was backed up early Friday afternoon. The photo shows vehicles stopped on the westbound side and a plow, headed west, on the eastbound side.
