CAS Number: 20667-12-3
Synonyms: Ag2O, Silver(I)Oxide, Argentic Oxide, Silver Monoxide
Formula Weight: 231.74 grams/Mole — (Contains 93.10% Silver)
Melting Point: 280°C ( 536°F ) – begins to release Oxygen to form Silver Powder.
Shelf Life: Indefinite when stored in it’s original bottle, securely capped.
This is a dry, brownish black powder that does absorb Carbon Dioxide from humid air.
It is best to buy it pre-ground and sifted (like ours).
Silver Oxide is not light sensitive. (as far as ordinary room lighting is concerned)
It is very slightly soluble in water. (.0002g / Liter @ 20°C)
Although not very soluble in water, it imparts a distinctly metallic taste to water.
It is soluble in dilute Nitric Acid.
It is reduced by Hydrogen gas at 100°C ( 212°F ), forming Silver Powder and water.
NOTE: All Metal Oxides form their respective Carbonates when exposed to Carbon Dioxide (in 25%+ humidity).
