Liver of sulfur decomposes to sulfate of potash and carbonate of potash, neither of which has any value as an oxidizer of metal. [2] The reactivity of liver of sulfur with silver and copper quickly creates a dark or colored patina on the metal. This is done by immersing the metal object in a solution of liver of sulfur and water.
Powdered potassium sulfide anhydrous. Potassium sulfide is an inorganic compound with the formula K 2 S.The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH).
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 ...
Saturated potassium nitrate solution is standard practice for humidity control in humid sulfur vapor testing. The saturated salt solution is placed physically outside of the sulfur containing dish. The sulfur containing dish may “float” in the saturated salt solution. The dish should provide an ample, available powdered sulfur surface.
Sulfites used in food processing (but not as a preservative) are required to be listed if they are not incidental additives (21 CFR 101.100(a)(3)), and if there are more than 10 ppm in the finished product (21 CFR 101.100(a)(4)) On July 8, 1986, sodium bisulfite (and other sulfites : "The chemicals affected by the order are sulfur dioxide ...

He called it "liquid sulfur" (flüssig Schwefel). [10] The composition of carbon disulfide was finally determined in 1813 by the team of the Swedish chemist Jöns Jacob Berzelius (1779–1848) and the Swiss-British chemist Alexander Marcet (1770–1822). [11] Their analysis was consistent with an empirical formula of CS 2. [12]
