Silver(I) sulfide. Silver and gold have rather low chemical affinities for oxygen, lower than copper, and it is therefore expected that silver oxides are thermally quite unstable. Soluble silver(I) salts precipitate dark-brown silver(I) oxide, Ag 2 O, upon the addition of alkali. (The hydroxide AgOH exists only in solution; otherwise it ...
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%).
Silver(I) oxide produced by reacting lithium hydroxide with a very dilute silver nitrate solution. Silver oxide can be prepared by combining aqueous solutions of silver nitrate and an alkali hydroxide. [8] [9] This reaction does not afford appreciable amounts of silver hydroxide due to the favorable energetics for the following reaction: [10]

Gold and silver are both precious metal assets worth investing in, but one could be a better bet right now. / Credit: Getty Images/iStockphoto Until recently, inflation had been high in the U.S.
