So I have a little silver oxide
And I have been trying to figure out other uses
Hopefully catalytic
It is quite slugish reacting with acetate acid
And sulfuric acid
Does silver oxide react with a hot potassium chlorate solution
To form potassium perchlorate
Supposedly silver oxide reacts with sodium chloride in ammonia to form sodium hydroxide I havnt be able to get this to work
Could silver carbonate be produced from desolving the silver oxide in ammonia and percipitating it with sodium bicarbonate
Forming silver carbonate
Also the same if silver chloride desolves in aqueous ammonia could silver carbonate precipitate with sodium bicarbonate
Is silver carbonate souble in ammonium hydroxide would be the final question
Sorry lots of question
Black solution of insouble black powder wont desolve in aquous ammonia

It might/should dissolve in lactic acid with maybe a little heating. Silver lactate solutions can then be a starting point for other silver salts,
possibly including the cool stuff like silver iodide. Silver lactate is soluble at about 7 grams per 100 milliliters of water. Lactic acid is used for
some purposes in beer making so is available at brewery stores in bags.
Sometimes silver/ammonia solutions can produce a black precipitate called silver nitride; it's unlikely unless the ammonia is quite concentrated but
if you do see this stuff you should be wearing a face-shield and heavy clothing as it is an explosive.
Another thing I've been thinking of trying is dissolving silver oxide in oxamic acid, which is made from monoammonium oxalate, i.e. ammonium hydrogen
oxalate NH4CO2CO2H. Silver oxamate's solubility is unpublished, but the paper in which oxamic acid was discovered suggested that silver oxamate is
actually very soluble in hot water, which is pretty cool, because most soluble silver salts are hard to make. For this you'll have to make oxamic acid
first: prepare a solution of oxalic acid, titrate with NaOH/phenolphthalein (or cabbage?) and remember to divide by 2 as it's diprotic. Mix with a
known solution of ammonia so that oxalic acid and ammonia are present in 1:1 molar ratio, evaporate water, and heat to 220-230 C where ammonium
bioxalate dehydrates to oxamic acid.

NB. the 446 degrees in the first book is Fahrenheit (446 F = 230 C). Anyway oxamic acid is then obtained by dissolving the residue in water, adding a
solution of Ca2+ or Ba2+, and collecting the precipitate calcium (or baryta) salt. Oxamic acid is liberated from the calcium salt by H2SO4. The
resulting oxamic acid can then form a silver salt whose solubility is unknown at present.

Silver oxide and chlorine gas forms silver chlorate apparently has anyone performed this
Tcca and silver oxide?

Attempted no reaction observed
oxalic acid
Ascorbic acid
Hydrofluoric acid
Hydrochloric acid
Adding ammonia first as catalysis might work
Have yet to try
Sodium metabisulfite
Citric acid
Sulfamic acid
Chloric acid
