How to make Silver Nitrate from Silver and Nitric acid.
WARNING: This reaction produces toxic nitrogen dioxide gas. Do not perform this reaction indoors, only do it in a fumehood or outside.
Simply place some pure silver in concentrated nitric acid and heat it up. The reaction proceeds too slowly in cold nitric acid to be useful.
Wrap your silver in aluminum wire to better control the reaction. If it proceeds out of control and fizzes too much or generates too much gas too fast then you can pull the silver out of the acid to stop the reaction.
Only aluminum is resistant to nitric acid, other metals are destroyed and will contaminate your acid.
We're going to use the silver nitrate to perform silver chloride photography, making mirrors, and even making flash powder.
