Qualitatively, decomposition is negligible below the melting point, but becomes appreciable around 250 °C and fully decomposes at 440 °C. [ 9 ] Most metal nitrates thermally decompose to the respective oxides , but silver oxide decomposes at a lower temperature than silver nitrate, so the decomposition of silver nitrate yields elemental ...
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ...
Silver sulfate precipitates as a solid when an aqueous solution of silver nitrate is treated with sulfuric acid: . 2 AgNO 3 + H 2 SO 4 → Ag 2 SO 4 + 2 HNO 3. It is purified by recrystallization from concentrated sulfuric acid, a step that expels traces of nitrate. [7]
Silver acetate can be synthesized by the reaction of acetic acid and silver carbonate. [3]2 CH 3 CO 2 H + Ag 2 CO 3 → 2 AgO 2 CCH 3 + H 2 O + CO 2. Solid silver acetate precipitates upon concentration of solutions of silver nitrate and sodium acetate.
For AgBr and AgI, the K sp values are 5.2 x 10 −13 and 8.3 x 10 −17, respectively. Silver bromide (slightly yellowish white) and silver iodide (bright yellow) are also significantly more photosensitive than is AgCl. [1] [4]: 46 AgCl quickly darkens on exposure to light by disintegrating into elemental chlorine and metallic silver.
US stocks ended Friday in the red, closing out a lackluster week despite a year of historic highs.. The Dow was lower by 333 points, or 0.78%, after the closing bell.
Silver nitrite is produced from the reaction between silver nitrate and an alkali nitrite, such as sodium nitrite. [3] Silver nitrite is much less soluble in water than silver nitrate, and a solution of silver nitrate will readily precipitate silver nitrite upon addition of sodium nitrite:
