how do I neutralize 2 oz silver nitrate to safely dispose of it?

Answer 1

Be careful handling silver nitrate as it can cause irreversible blindness if you get it in your eyes!!!!!!!!

Make a solution of table salt, NaCl, and add this to the silver nitrate until no more white precipitate is formed. This will convert the 'lunar caustic' (silver nitrate) to silver chloride which is insoluble. It can then be disposed of by turning it in to a hazardous waste disposal company or hire someone to properly dispose of it. Caution: make sure that the person or company is legitimate and that they do not just dump it in the city trash.

Assuming a 100% clean reaction where all silver in the silver nitrate solution precipitates out, you would need approximately 49 grams of silver nitrate to yield one Troy ounce of pure silver. Silver nitrate is 63.5% pure silver. I don't know how much copper would be required. But, the first answer was correct in that it would be much less expensive to just buy an ounce of silver. A 50-gram bottle of AgNO3 goes for $75-$80.

Answer 5

You may be able to neutralize it, but silver nitrate and the trace lead it contains are considered hazardous waste.

Ask your local camera shop if they have a means of disposal.

Otherwise, call your extension office or even the fire department, they have a list of how wastes should be handled.

Answer 6

Silver nitrate will stain the skin. It is actually was used in babies eyes(very dilute) to kill bacteria that cause blindness that get on the babies eyes in the birth canal. (they have changed to antibiotics)
If you want to get rid of it, put in some copper and the silver will precipitate out leaving copper nitrate, blue. Copper nitrate is sometimes used in ponds to control algae. If there is a film manufacturer near you they may take it as they recycle silver from thei processing.

Answer 7

In a legal sense, you cannot dispose of it, because it is a compound of a toxic metal. Your community may have a "hazardous household wastes disposal program." If so, take it there. Photo labs (even those who print digital photos) have silver wastes, which they send back to processors, who reclaim the silver values and send silver metal back to companies who deal in precious metals. It may be that you can give it to one of the photo labs. Whatever you do, do not bury the silver waste on your property next to the grave of Kitty. Doing this may make your property a Superfund site.
