yes, silver nitrate kept out of light and humdity is very stable. I also
think that it is easier and cheaper in the long run to buy silver oxide
than make it. I made silver nitrate once. It was not a nice experience.

Silver nitrate when used in the right dilution is an antiseptic. The silver
nitrate content is something like in the parts per thousand for medicinal
use. The syphillis idea is sort of correct, probably the most common reason
during the post WWII years with all the returning vets. Silver nitrate
compounds are still used as a topical antiseptic today.
